Abstract: Perylene compounds (A) are new. Perylene compounds (A) of formulae (I) and (II) are new. R1-R11 : H or linear alkyl radical having at most 37 C, in which 1-10 CH 2units are optionally replaced by carbonyl groups, O, S, Se, Te, cis- or trans-CH=CH-groups, in which the CH-units are optionally replaced by N, acetylenic C?=C-groups, 1,2-, 1,3- or 1,4-substituted phenyl, 2,3-, 2,4-, 2,5-, 2,6-, 3,4- or 3,5-disubstituted pyridine, 2,3-, 2,4-, 2,5- or 3,4-disubstituted thiophene, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 2,3-, 2,6- or 2,7-disubstituted naphthalene, in which one or two CH-groups are optionally replaced by N, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 1,9-, 1,10-, 2,3-, 2,6-, 2,7-, 2,9-, 2,10- or 9,10-disubstituted anthracene, in which one or two CH-groups are optionally replaced by N; and X : chemical bond or 1-12 CH 2-units, which are optionally replaced by carbonyl, O, S, Se, Te, cis- or trans-CH=CH-groups, in which CH-units are optionally replaced by N, acetylenic C?=C-groups, 1,2-, 1,3- or 1,4-substituted phenyl, 2,3-, 2,4-, 2,5-, 2,6-, 3,4- or 3,5-disubstituted pyridine, 2,3-, 2,4-, 2,5- or 3,4-disubstituted thiophene, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 2,3-, 2,6- or 2,7-disubstituted naphthalene, in which one or two carbon atoms are optionally replaced by N, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 1,9-, 1,10-, 2,3-, 2,6-, 2,7-, 2,9-, 2,10- or 9,10-disubstituted anthracene, in which one or two CH-groups are optionally replaced by N, where in R1-R11 and X, up to 12 individual H of the CH 2-groups or the alkyl groups are optionally replaced at the carbon atom by halo comprising F, Cl, Br or I or CN or linear alkyl chain having up to 18 C, in which 1-6 CH 2-units are optionally replaced by carbonyl, O, S, Se, Te, cis- or trans-CH=CH-groups, in which CH-units are optionally replaced by N, acetylenic C?=C-groups, 1,2-, 1,3- or 1,4-substituted phenyl, 2,3-, 2,4-, 2,5-, 2,6-, 3,4- or 3,5-disubstituted pyridine, 2,3-, 2,4-, 2,5- or 3,4-disubstituted thiophene, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 2,3-, 2,6- or 2,7-disubstituted naphthalene, in which one or two carbon atoms are optionally replaced by N, 1,2-, 1,3-, 1,4-, 1,5-, 1,6-, 1,7-, 1,8-, 1,9-, 1,10-, 2,3-, 2,6-, 2,7-, 2,9-, 2,10- or 9,10-disubstituted anthracene, in which one or two carbon atoms are optionally replaced by N, where in the place of substituents, the free valences of the methine groups or quaternary C-atoms are linked in pairs to form rings such as cyclohexane ring, and the R1-R9 also represents halo. Independent claims are included for: (1) a micellar solution comprising (A) in aqueous phase, where the micelle former is 1-dodecyl sulfate, 1-dodecylsulfonate, Nekal(RTM: 2,3-Dimethylnaphthalen-4-sulfonate) or Bomol 4N(RTM: Maleated linseed oil); and (2) producing nanomicellar comprising preparing a gel from the micelle former, distributing the gel in water under the simultaneous action of ultrasound.
