Description: The present invention concerns new chemical compounds which contain a substituent which can be considered as "highly fluorinated", their preparation and their application as surfactants, in particular in compositions intended for biomedical employment as oxygen carriers, administrable intravascularly or through other routes. Such compositions and certain of their applications have been described by M. LE BLANC and J.G. RIESS, in "Preparation, Properties and Industrial Applications of Organofluorine Compounds, Chap. 3, R.E. BANKS Ed., Ellis Horwood Ltd., Chichester, 1982". Among these compositions, one can cite those which are themselves fluorocarbon-based and are usable as blood and plasma substitutes, preparations for the treatment of cerebral and cardiac ischemia or for sensitization of tumors to radiation or chemotherapeutic agents, cardioplegic and reperfusion solutions, diagnostic agents, and non intravascular oxygenating agents, for example for preservation of isolated organs and tissues, or for perfusion of the brain by the ventriculo-sub-arachnoid route. The applications of these new compounds can be attributed to their surfactant and biocompatibility properties. Furthermore, they can be used as a co-surfactants, when a small proportion induces a synergistic effect with another surfactant of a different nature, such as lecithins or alkylene oxide block polymers similar to those marketed under the "Pluronic" trademark, in any application where at least one surfactant is required. For several years, fluorocarbon emulsions have been described, in which synthetic chemical compounds assure, in particular the transport of oxygen to the tissues, and of carbon dioxide to the lungs, and some of which can simultaneously fulfill still other functions, such as those of a diagnostic contrast agent, a vehicle for nutritive and/or medicinal substances or analogues thereof. These compounds belong to the general class of fluorocarbon and perfluoralkylated derivatives, in a broad sense, and, due to their insolubility in plasma or water, they must be maintained in an emulsion by means of one or more surface active agents. Nevertheless, despite the progress made in this field, a certain number of difficulties and drawbacks remain, that have not been resolved, as described by J.G. Riess in "Artificial Organs", Vol. 8 (1), pp. 44-56 (1984), as well as in the periodical "Life Support Systems", vol. 2 (4), pp. 273-276 (1984). US-A-3952 066 discloses compounds, useful as surface active agents for industrial use, which are derived from glycerol monoallylethers, wherein the allyl moiety is attached to a perfluoroalkyl group and wherein one of the two remaining hydroxy group of glycerol may be further derivatized. US-A-4089 804 discloses a method of improving the surface tension property of a cationic, anionic, non-ionic, amphoteric or mixed fluorinated surfactant, by incorporating therewith a fluorinated synergist. In fact, the properties of the surfactants known and in use to date are still insufficient for the mastery of the emulsions, especially with regard to their intravascular persistence and their stability. Furthermore, many surfactants are toxic and they are obviously not biomedically acceptable. Thus, even the lecithins, whose use is widely advocated in this field, are not very stable and can produce toxic decomposition or oxydation products. The present invention rests on the discovery that a particular family of surfactants and co-surfactants belonging to the new class discussed herein, does not suffer these disadvantages but possesses, on the contrary, properties which are particularly appropriate to the aforementioned applications. The present invention relates to chemical compounds having a polyhydroxylated hydrophilic moiety, a highly fluorinated moiety and a functional junction group linking said moieties together, wherein said hydrophilic moiety is derived from a polyol or an aminopolyol, and wherein said highly fluorinated moiety consists of a fluorocarbon group wherein at least 50% (and particularly at least 60%) of the atoms bonded to the carbon skeleton are fluorine atoms, the other atoms bonded to the carbon skeleton being hydrogen, chlorine or bromine atoms, said highly fluorinated moiety containing at least 4 (and generally 5) fluorine atoms ; as well as the internal ethers and ketals thereof.. The functional junction group is for example one which allows to link the hydrophilic and fluorinated moieties through an ether, ester, amide or amine group. The hydrophilic moiety is derived from a monosaccharide (such as aldopentoses, ketopentoses, aldohexoses, ketohexoses, 6-deoxyaldohexoses, 6-deoxyketohexoses), from a polyol (other than a sugar) containing at least 4 hydroxyl groups (such as pentitols, 1-deoxyhexitols, hexitols, cyclitols), from an aminopolyol having at least 3 hydroxyl groups (such as 1-amino-1-deoxypentitols, osamines, 2-amino-2-deoxypentitols, 1-amino-1,6-dideoxyhexitols, 1-amino-1-deoxyhexitols), or from a disaccharide (such as maltose, lactose, saccharose or cellobiose). The highly fluorinated moiety (R F ) may be introduced for example as a R F -W- group, wherein R F is selected from the group consisting of : R F 1 being CF₃-, C₂F₅- or (CF₃)₂CF-, R F 2 and R F 3, identical or different, being selected from CF₃-, C₂F₅-, n-C₃F₇ or CF₃CF₂CF(CF₃)-, CF₃CF₂O(CF₂CF₂O) t CF₂- 0 ≦ t ≦ 6 and CF₃(CF₂)₂O [CF(CF₃)CF₂O] u CF(CF₃)- 0 ≦ u ≦ 6 and W is selected from the group consisting of : (wherein in the last three cases R F is bonded to the carbon atom of the left end of the W group), wherein n may vary from 1 to 12, m may vary from 0 to 12, the sum (p+q) may vary from 1 to 12, j and k may vary from 1 to 12, it being understood that W can still contain a -(CH₂CH₂O) y -polyoxyethylene-type, a [CH(CH₃)CH₂O] y polyoxypropylene-type or a -(CH₂CH₂S) y - polythioethylene-type segment, or a mixture of such segments, with 1 ≦ y ≦ 12, and that in the R F - chain, part of the fluorine atoms can be replaced by H, Cl or Br atoms, in a proportion such that at least 50% of the atoms bonded to the carbon skeleton of R F - are fluorine atoms, with at least 4 fluorine atoms being present in said chain. When R F -W- is an acyl group, i.e. when W is -(CH₂) m -CO-, it may be linked with the hydrophilic moiety either by an ester bond (formed with a hydroxyl group of the hydrophilic moiety) or by an amide bond (formed with an amine group of the hydrophilic moiety). In the other cases, R F -W- is linked with the hydrophilic moiety through an ether bond or a -N(R″)- amine bond, wherein R″ may represent -H, C₁-C₁₈ alkyl, C₂-C₁₈ unsaturated alkyl, or R″ may represent a R F -W- group as defined above. Preferably, the compounds according to the present invention contain 1 or 2 R F -W- groups ; also preferably, at least 60% of the atoms linked to the carbon skeleton of R F are fluorine atoms, and R F carries at least five fluorine atoms. The invention particularly relates to the compounds, as defined above, wherein R F is a perfluorinated group. The compounds according to the invention comprise those which are derived from the substitution, by a highly fluorinated substituent, of at least one of the hydrogen atoms of the hydroxyl or amino groups carried by a compound of the formula (II) X-Y-CH(OH)-CH(OH)-CH(OH)-Z (II) wherein X, Y and Z are as defined hereafter. Thus, the invention relates particularly to the compounds of the formula I X-Y-CH(OR₁)-CH(OR₂)CH(OR₃)-Z (I) wherein : X represents -CH=O, -CH₂OR₄, -CH₂N(R₅)R₆ or -CH(OR₇)-, Y represents -CH(OR₈)-, -CO- or -CH(NR₅R₆)-, Z represents -H, -CH₃, -CH₂OR₉ or -CH(OR₁₀)-, it being understood that : when X is -CH=O, then Y represents -CH(OR₈)- or -CH(NR₅R₆)-, when X is -CH₂N(R₅)R₆, then Y represents -CH(OR₈)-, when Z is -CH(OR₁₀)-, then X represents -CH(OR₇)- and then the divalent groups X and Z are linked together through a covalent bond, and when Y is -CH(NR₅R₆)-, the X represents -CH=0 or -CH₂OR₄, and the R₁ to R₁₀ groups, which may be identical or different, are selected from -H, C₁-C₁₈ alkyl, C₂-C₁₈ unsaturated alkyl, a deoxy-oside group, a -(CH₂CH₂O) y -H, or (CH₂CH₂S) y -H group, or a mixture of said groups, wherein 1 ≦ y ≦ 12, and a highly fluorinated group as defined above, with the proviso that at least one of the R₁ through R₁₀ groups represents a group having a highly fluorinated substituent, said group being for example of the R F -W- type as defined above ; as well as internal ethers and ketals thereof. The invention relates particularly to the compounds of formula I wherein the non-fluorinated R groups attached to oxygen atoms of the polyol or amino-polyol represent -H. Of course, when one of the R substituents is a deoxy-oxide group, the basic hydrophilic moiety is a diholoside, and each sugar moiety of the diholoside may carry a highly fluorinated substituent. In many cases, the compounds of formula I may comprise open forms, tautomeric or analogous forms, or cyclic derivative structures, as described for example in the "Handbook of Biochemistry and Molecular Biology, Lipids, Carbohydrates, Steroids", 3rd Ed., CRC Press, 1975. The formula I likewise implies no limitation at all with regards to a particular stereochemistry. For example, when X represents CHO, and Y is CHOH, the compounds of formula I are derived from an aldose type sugar, the structure of which can adopt the tautomeric forms (IA), (IA₁) and (IA₂) : the structure (IA) representing the open form, while the structures (IA₁) and (IA₂) represent the cyclic (or acetal) forms, i.e. a pyranose (IA₁) and a furanose (IA₂), respectively. In this first case, if in formula (IA), Z represents CH₂OH, the formula represents the various hexoses, such as glucose, galactose, mannose, etc. ; Z represents H, the formula represents the various pentoses, such as ribose, arabinose, xylose, etc. ; Z represents CH₃, the formula represents the various deoxy-6-hexoses, such as rhamnose, fucose etc. Likewise, when, in the formula I, X represents CH₂OH, then two cases are possible : In the case where Y represents C=O, one obtains a family of cetose type sugars whose basic structures can adopt the open (IB), and the cyclic (IB₁) and (IB₂) tautomeric forms, which in the example where Z equals CH₂OH, are the hexocetoses which have the following structures : These structures are those of diverse hexocetoses, of which fructose is a typical example, structure (IB₁) representing its pyranose form and structure (IB₂) reprsenting its furanose form. Other sugars in this family are those resulting from the association of compounds derived from those represented by formulas (IA) and/or (IB), such as, for example, sucrose, lactose, maltose and cellobiose. in the case where Y represents CHOH, the basic structure represents the family of polyols (IC) when Z represents CH₂OH, the basic structure is that of hexitols such as, for example, mannitol, sorbitol, etc., when Z represents H, the basic structure is that of pentitols such as, for example xylitol, and when XZ represents (CHOH)₂, the basic structure is that of cyclitols, of formula (ID) : such as for example inositol. The aforementioned hexitols (IC), by dehydration, lead to the manoanhydrides (II A), then to the dianhydrides (II B) according to the following diagram : when X represents CH₂NH₂ or CH₂N(R₅)R₆ and therefore Y represents CHOH, the basic structure represents the aminopolyols, of which glucamine IE is a good example, in which Z represents CH₂OH It goes without saying that all of the isomers represented by the preceding various formulas are included in the scope of the present invention. One should also note that when a substituent R represents another saccharide radical, this radical can derive in particular from glucose, galactose or fructose, and have pyranose of furanose cyclic forms such as, for example, the following : in which the substituents R′ and Z′ have (independently) the same significance as Z and the corresponding R substituents in formula I. in this case, the basic hydrophilic moiety is derived from a diholoside. Another object of the present invention is a process for the preparation of the new compounds as defined above. Said process is essentially characterized by the fact that the starting material is said polyol or aminopolyol, or a derivative thereof, including internal ethers or ketals thereof, wherein the hydroxyl groups, or part thereof, are protected, or wherein at least one hydroxyl group is replaced by a leaving group, that said starting material is reacted with a highly fluorinated derivative, in a manner known per se, so as to link the polyol or aminopolyol moiety with the highly fluorinated moiety through a functional junction group, and that the protected groups, when present, are deprotected according to usual methods. The highly fluorinated derivative may be for example an alcohol, an amine, an anhydride, a mixed anhydride or an acyl chloride. The leaving group may be for example a halogen (other than fluorine, preferably bromine) or an activated alcohol derivative such as a tosylate, mesylate or triflate group. Such a derivative with a leaving group will react with the highly fluorinated derivative (in the form of an alcohol or an amine) to form a corresponding ether or amine bond. When the highly fluorinated group is present in the form of a R F -W- group as defined above, the process of the invention is essentially characterized by the fact that the hydrophilic starting material, as defined above, is reacted with a member of the group consisting of : (a) an alcohol R F -W-OH, where R F -W- is other than acyl, (b) an amine R F -W-NH(R″), where R F -W- is other than acyl, R″ being -H, C₁-C₁₈ alkyl, C₂-C₁₈ unsaturated alkyl or R F -W- and where the hydrophilic starting material has a leaving group, (c) a mixed anhydride R F -W-O-CO-OAlk, Alk being lower alkyl, or an acyl chloride R F -W-Cl where R F is an acyl and where the starting material is an aminopolyol, and (d) an acylchloride R F -W-Cl, where R F -W- is acyl, so as to obtain: in cases (a) and (d) respectively an ether or ester of the type R F -W-O-(hydrophilic moiety), and in cases (b) and (c) respectively an amine or amide of the type R F -W-N(R″)-(hydrophilic moiety), and by the fact that the protected groups, when present, are subjected to a deprotection reaction according to known methods. In case (c), when the starting material is reacted with the acylchloride, the -OH groups must be protected in order to obtain the desired amide. The invention relates particularly to a process for the preparation of compounds of formula I, wherein : either the starting material is a compound similar to a compound of formula I, but having no highly fluorinated group, and R₅ and R₆, when present, are different from -H, and wherein the -OH groups of said starting material which are not desired to be substituted are temporarily protected, said starting material is reacted with an acylchloride R F -W-Cl (when R F -W- is an acyl) or with a compound R F -W-Z′ (when R F -W- is different from an acyl), where Z′ is -OH or a leaving group, so as to obtain respectively the corresponding ester or ether of formula I, and then the protected groups are subjected to a deprotection reaction ; or the starting material is a compound similar to a compound of formula I, but having no highly fluorinated group, wherein at least one of the -OR₁, -OR₂, -OR₃, -OR₄, -OR₇, -OR₉, OR₁₀ or -NR₅R₆ groups is replaced by a leaving group, and wherein the -OH groups are protected, said starting material is reacted with an alcohol R F -W-OH or amine R F -W-NHR″, wherein R F -W- is other than acyl and R″ is -H, C₁-C₁₈ alkyl, C₂-C₁₈ unsaturated alkyl, or R F -W-, so as to obtain a corresponding compound of formula I wherein the leaving group of the starting material is replaced respectively by a -O-W-R F or -N(R″)-W-R F substituent, and then the protected groups are subjected to a deprotection reaction ; or the starting material is a compound similar to a compound of formula I, having a -NR₅R₆ group, but having no highly fluorinated group, wherein at least one of R₅ and R₆ is -H, said starting material is reacted with a mixed anhydride of the formula R F -W-O-CO-OAlk (R F -W-being an acyl and Alk being lower alkyl), so as to obtain a corresponding amide of formula I having a -NR₅(R F W), -NR₆(R F W) or -N(R F W)₂ group. When the resulting product of formula I is an ether having a R F -W-O-group, W representing an unsaturated alkyl of the formula -CH₂) p -CH=CH-(CH₂) q -, said product may be converted into another compound of formula I by reduction of the double bond, according to known methods. The corresponding compound thus obtained is one where W represents -(CH₂)- p+q+2 . For preparing a compound of formula I, where W is -(CH₂) p -CH=CH-(CH₂) q -, with q=0, the starting material is etherified with the alcohol HO-(CH₂) p -CH=CH₂. By reacting said alcohol with a halide R F -W-Hal (wherein Hal is halogen other than fluorine, for example iodine), there is obtained a corresponding ether of the type -O-(CH₂) p -CH=CH-R F which may be reduced, if desired, to the corresponding ether of the type -O-(CH₂) p+2 -R F . In a general manner, the -OH groups to be protected in the starting material can be protected in the form of esters. When the starting material has a leaving groups (such as bromine), in the anomeric position and the next carbon atom has a hydroxyl groups protected as an ester (for example an ester of the type Alk-CO-O-, Alk being lower alkyl), the reaction of the alcohol R F -W-OH on the starting material gives as an intermediate product an ortho ester according to the reaction : By rearrangement in the presence of HgBr₂ in anhydrous medium, the ortho-ester is then converted into the corresponding -OWR F ether of the partial formula : The obtained compounds which contain temporarily protected hydroxyl groups may be subjected to a deprotection reaction according to the known techniques. When the starting material has a leaving group which is a halogen (other than fluorine, for example bromine), the reaction with the alcohol R F -W-OH, for obtaining an ether bond, may be carried out according to the known method of Koenigs-Knorr (or the known variations thereof) in the presence of a silver salt, such as silver carbonate, or of silver oxide. In this case, the hydroxyl groups which are not to be etherified are protected in the form of esters. Moreover, when the starting material contains cis vic-glycol groups, the hydroxyl groups of said vic-glycols may be temporarily protected in the form of acetonides, according to the known methods. The isolated hydroxyl groups remain unprotected and may then be etherified or esterified by a R F W- group. Of course, the starting materials may be used in the form of the internal ethers (anhydrides) or ketals of the products of formula I. The invention also relates to the use of the highly fluorinated compounds as defined above, including the compounds of formula I, and mixtures thereof, as surfactants or co-surfactants. Said surfactants may be used especially in biomedical preparations as described above. The invention also relates to compositions in the form of, solutions, dispersions, gels, emulsions and microemulsions in water or any other polar solvent, containing non polar substances and compounds such as oils, hydrocarbonated or not, and incorporating at least one hydrophilic and fluorinated compound as defined above, and optionally another surfactant. The said non polar substances, compounds or oils may be highly fluorinated or perfluorinated. In such compositions, said highly fluorinated or perfluorinated compound or substances, with molecular masses between about 400 and 700, may be chosen especially among at least of the following : the bis(F-alkyl)-1,2-ethenes and more particularly the bis(F-butyl)-1,2-ethenes, the F-isopropyl-1-F-hexyl-2-ethenes and the bis(F-hexyl)-1,2-ethenes, the perfluorodecalins, the perfluoro-methyldecalins, the perfluoro-dimethyldecalins, the perfluorodimethyladamantanes, the perfluorotrimethylbicyclo-/3,3,1/nonanes and their homologues, ethers of formula (CF₃)CFO(CF₂CF₂) OCF(CF₃)₂, (CF₃)₂CFO(CF₂CF₂)₃OCF(CF₃)₂, (CF₃)₂-CFO(CF₂CF₂)₂F, (CF₃)₂CFO(CF₂CF₂)₃F, F[CF (CF₃)CF₂O]₂ CHFCF₃, (C₆F₁₃)₂O, the amines N(C₃F₇)₃, N(C₄F₉)₃, the perfluoromethylquinolidines and perfluoroisoquinolidines, the halogen derivatives C₆F₁₃Br, C₈F₁₇Br, C₆F₁₃CBr₂CH₂Br, 1-bromoheptadecafluoro-4-isopropylcyclohexane and analogues, it being understood that the compounds can be used separately or in the form of mixtures. Such compositions are more particularly used as gas carriers, and in particular for oxygen, in living surroundings, for human and veterinary medical applications, in particular as blood substitutes, contrast agents, means to treat cerebral and cardiac ischemia, for the preservation of organs, tissues, embryos, semen, medium usable in cardiovascular therapy and surgery, for example as a cardioplegic, reperfusion, or coronary angioplasty solution, medium usable as adjuvant for radiotherapy or chemotherapy of cancer, or medium usable as medicinal vehicle. Typically, the compositions of the present invention consist essentially of 5-70 % (vol/vol) of said non polar compound, and 0,5-12 % (vol/vol) of at least one surfactant, and the remainder being the solvent, e.g. water. The surfactant consists of at least one of the polyhydroxylated and highly fluorinated surfactants of the present invention, optionally in combination with conventional surfactants, said fluorinated surfactants representing, by volume, from 5 % to 100 % of the total volume of surfactants. The composition may also comprise usual additives, including inorganic salts, generally in the form of buffers, which allow to adjust the pH and to obtain an isotonic composition. Among the polyhydroxylated highly fluorinated surfactant compounds of the invention, there may be used especially one of the following : the 2′-(F-hexyl)-ethyl-β-D-glucopyranoside, the 2′-(F-hexyl)-ethyl-α-D-glucopyranoside, the 2′-(F-octyl)-ethyl-β-D-glucopyranoside, the 2′-(F-octyl)-ethyl-α-D-glucopyranoside, the 2′-(F-hexyl)-ethyl-β-D-galactopyranoside, the 2′-(F-hexyl)-ethyl-α-D-galactopyranoside, the 3′-(F-hexyl)-propyl-β-D-xylopyranoside, the 3′-(F-hexyl)-propyl-β-L-rhamnopyranoside, the 2′-(F-butyl)-ethyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 2′-(F-butyl)-ethyl-β-D-maltopyranoside, the 2′-(F-hexyl)-ethyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 2′-(F-hexyl)-ethyl-β-D-maltopyranoside, the 2′-(F-hexyl)-ethyl-4-O-(α-D-glucopyranosyl)-α-D-glucopyranoside, or 2′-(F-hexyl)-ethyl-α-D-maltopyranoside, the 2′-(F-octyl)-ethyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 2′-(F-octyl)-ethyl-β-D-maltopyranoside, the 2′-(F-octyl)-ethyl-4-O-(α-D-glucopyranosyl)-α-D-glucopyranoside, or 2′-(F-octyl)-ethyl-α-D-maltopyranoside, the 3′-(F-butyl)-propyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 3′-(F-butyl)-propyl-β-D-maltopyranoside, the 3′-(F-hexyl)-propyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 3′-(F-hexyl)-propyl-β-D-maltopyranoside, the 3′-(F-octyl)-propyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 3′-(F-octyl)-propyl-β-D-maltopyranoside, the 11′-(F-butyl)-undecyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 11′-(F-butyl)-undecyl-β-D-maltopyranoside, the 11′-(F-hexyl)-undecyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 11′-(F-hexyl)-undecyl-β-D-maltopyranoside, the 11′-(F-octyl)-undecyl-4-O-(α-D-glucopyranosyl)-β-D-glucopyranoside, or 11′-(F-octyl)-undecyl-β-D-maltopyranoside, the 2′-(F-hexyl)-ethyl-4-O-(β-D-galactopyranosyl)-β-D-glucopyranoside, or 2′-(F-hexyl)-ethyl-β-D-lactopyranoside, the 2′-(F-octyl)-ethyl-4-O-(β-D-galactopyranosyl)-β-D-glucopyranoside, or 2′-(F-octyl)-ethyl-β-D-lactopyranoside, the 2′-(F-octyl)-ethyl-4-O-(β-D-glucopyranosyl)-β-D-glucopyranoside, or 2′-(F-octyl)-ethyl-β-D-cellobiopyranoside, the 6-O-|3′-(F-butyl)-2′-propenyl|-D-galactose, the 6-O-|3′-(F-hexyl)-2′-propenyl|-D-galactose, the 6-O-|3′-(F-octyl)-2′-propenyl|-D-galactose, the 3-O-|3′-(F-butyl)-2′-propenyl|-D-glucose, the 3-O-|3′-(F-hexyl)-2′-propenyl|-D-glucose, the 3-O-|3′-(F-octyl)-2′-propenyl|-D-glucose, the 6-O-|3′-(F-butyl)-propyl|-D-galactose, the 6-O-|3′-(F-hexyl)-propyl|-D-galactose, the 6-O-|3′-(F-octyl)-propyl|-D-galactose, the 3-O-|3′-(F-butyl)-propyl|-D-glucose, the 3-O-|3′-(F-hexyl)-propyl|-D-glucose, the 3-O-|3′-(F-octyl)-propyl|-D-glucose, the 3-O-|3′-(F-pentyl)-propanoyl|-D-glucose, the 3-O-|3′-(F-heptyl)-propanoyl|-D-glucose, the 3-O-|3′-(F-octyl)-propanoyl|-D-glucose, the 6-O-|3′-(F-pentyl)-propanoyl|-D-galactose, the 6-O-|3′-(F-heptyl)-propanoyl|-D-galactose, the 6-O-|3′-(F-octyl)-propanoyl|-D-galactose, the 3-O-|11′-(F-hexyl)-undecanoyl|-D-glucose, the 6-O-|11′-(F-butyl)-undecanoyl|-D-galactose, the 6-O-|11′-(F-hexyl)-undecanoyl|-D-galactose, the 6-O-|11′-(F-octyl)-undecanoyl|-D-galactose, the 3-O-|3′-(F-octyl)-propanoyl|-D-xylose, the 6-O-|3′-(F-octyl)-propanoyl|-D-fructose, the 1-O-|3′-(F-octyl)-propanoyl|-D-fructose, the 6-D-fructofuranosyl-6-O-|3′-(F-octyl)-propanoyl|-α-D-glucopyranoside or 6-O-|3′-(F-octyl)-propanoyl|-sucrose, the 6-O-|3′-(F-octyl)-propanoyl|-β-D-fructopyranosyl 6-O-|3′-(F-octyl)-propanoyl|-α-D-glucopyranoside, or 6,6′-di-|3′-(F-octyl)-propanoyl|-sucrose, the 5-O-|3′-(F-butyl)-2′-propenyl|-xylitol, the 5-O-|3′-(F-hexyl)-2′-propenyl|-xylitol, the 5-O-|3′-(F-octyl)-2′-propenyl|-xylitol, the 5-O-|3′-(F-butyl)-propyl|-xylitol, the 5-O-|3′-(F-pentyl)-propanoyl|-xylitol, the 5-O-|3′-(F-heptyl)-propanoyl|-xylitol, the 5-O-|3′-(F-octyl)-propanoyl|-xylitol, the 5-O-|11′-(F-hexyl)-undecanoyl|-xylitol, the 3,4-di-O-|3′-(F-octyl)-propanoyl|-D-mannitol, the 2-O-|3′-(F-pentyl)-propanoyl|-1,4:3,6-dianhydro-D-mannitol, the 2-O-|3′-(F-octyl)-propanoyl|-1,4:3,6-dianhydro-D-mannitol, the 2-O-|3′-(F-octyl)-propanoyl|-1,4:3,6-dianhydro-D-sorbitol, the 5-O-|3′-(F-octyl)-propanoyl|-1,4:3,6-dianhydro-D-sorbitol, the 6-O-|3′-(F-octyl)-propanoyl|-1,4-D-sorbitan, the 6-O-|11′-(F-octyl)-undecanoyl|-1,4-D-sorbitan, the |3′-(F-pentyl)-propanoyl|-N-methyl-D-glucamide, the |3′-(F-heptyl)-propanoyl|-N-methyl-D-glucamide, the |3′-(F-octyl)-propanoyl|-N-methyl-D-glucamide, the 2-deoxy-2-|3′-(F-octyl)-propanamido|-D-glucose, the 2-deoxy-2-|3′-(F-octyl)-propanamido|-D-glucitol, the 3-O-|3′-(F-octyl)-propanoyl|-myo-inositol. EXAMPLES The following examples illustrate these diverse possibilities, being understood that the compounds described are only some of those which can be obtained, and that they can be obtained also by yet other methods than those listed hereunder, which are only some of the various possible preparation methods. Likewise these processes can apply just as well to optically pure compounds as to mixtures of stereoisomers. Example 1 : 2′-(F-hexyl)-ethyl-D-glucopyranoside, 3α and 3β Step 1: Preparation of the orthoester, 1 8.22 g (20 mmol) of tetra-O-acetyl-α-D-glucopyranosyl bromide dissolved in 20 ml of anhydrous nitromethane are treated under argon with 14.9 g (41 mmol) of 2-(F-hexyl)-ethanol and 4 ml of anhydrous 2,6-lutidine at 25°C.

Surfactant activity The strong surface activity of the compounds encompassed by this invention is illustrated in particular by the strong lowering of the surface tension (γ s ) they cause when added to water, as shown by the examples of surface tensions, measured at 20°C and expressed in milliNewton.metre⁻¹, (mNm⁻¹), collected in the Table below: More specifically, the action of these compounds at the interface between water and the fluorocarbons is demonstrated by the very sharp diminution of the interfacial tension (γ i ) between water and perfluorodecalin (56 mNm⁻¹ in the absence of surfactant), as illustrated by the examples collected in the same Table. The co-surfactant character of the compounds concerned by the invention is illustrated in particular by the sharp diminution of the surface tension (γ s ) they provoke when added to a solution in water of 1g/l of Pluronic F-68 (a commercial surfactant used in the preparation of emulsions of fluorocarbons for biomedical use, such as Fluosol-DA or Oxypherol) from γ s = 47±0,3 mNm⁻¹ to the values collected for a few examples in the Table below: More specifically, the action of these compounds on the interface between water and fluorocarbons is demonstrated by the very sharp diminution of the interfacial tension (γ i ) between dispersions of these compounds in a solution of Pluronic F-68 at 1 g/l in water and perfluorodecalin. The interfacial tension is thus lowered from γ i = 31 mNm⁻¹ with Pluronic F-68 alone, to the values collected in the same Table. The stabilisation effect which can be obtained on the emulsions by incorporating the new surfactants is illustrated, for example, by the fact that the increase in particle size is 6 times less after 30 days at 50°C for a 20% weight/volume emulsion of F-decalin prepared with 2% (w/v) of Pluronic F-68 and 1% (w/v) of 5-O-|3′-(F-octyl)-2′-propenyl|-xylitol, 35, as surfactants, than for a reference emulsion prepared similarly but with 3% of Pluronic F-68 as the sole surfactant. It is also noteworthy that the particle size is still smaller in the fluorinated surfactant-containing emulsion maintained at 50°C for 30 days than for the reference emulsion stored at 4°C for the same length of time. The biocompatability of compounds belonging to the present invention is illustrated, in particular, by the fact that aqueous solutions of these compounds, and dispersions of these compounds in aqueous solutions of Pluronic F-68, for example: a solution of 0.1 g/l of 2′-(F-hexyl)-ethyl-D-glucopyranoside, 3, a solution of 0.1 g/l of |3′-(F-octyl)-propanoyl|-N-methyl-D-glucamide, 51, a solution of 0.1 g/l of 6-O-|3′-(F-butyl)-2′-propenyl|-D-galactose, or a dispersion of 1 g of 2′-(F-octyl)-ethyl-D-maltopyranoside, 29, in a solution of 1 g/l of Pluronic F-68 in water, all these solutions and dispersions containing 9%o of NaCl, do not perturb the growth and multiplication of lymphoblastoid cell cultures of the Namalva strain. Likewise, the biocompatability of compounds belonging to the invention is illustrated by the fact that aqueous solutions of 100 g/l of 2′-(F-hexyl)-ethyl-D-maltopyranoside, 26, or of 1 g/l of 6-O-|3′-(F-butyl)-2′-propenyl|D-galactose, or a dispersion of 1 g/l of 2′-(F-octyl)ethyl-D-maltopyranoside, 29, in a solution of 1g/l of Pluronic F-68 in water, or a dispersion of 16 g/l of 6-O-|3′-(F-hexyl)-2′-propenyl|-D-galactose, 33, in a solution of 1 g/l of Pluronic F-68 in water, or a dispersion of 20 g/l of 5-O-|3′-(F-octyl)-2′-propenyl|-xylitol, 35, in a solution of 10 g/l of Pluronic F-68 in water, all these solutions and dispersions containing 9%o of NaCl, do not cause the hemolysis of human red blood cells.
