Claim 0:
1. A silane of formula I):

(R″))Si—R2-X-A-Y—[R′—Y-]n-R′—S-G,  I)

wherein o can be 1, 2 or 3; and,
the radicals R1 within the silyl groups (R1)oSi— are identical or different from each other and are selected from alkoxy groups having 1 to 10 carbon atoms, cycloalkoxy groups having 4 to 10 carbon atoms, phenoxy groups having 6 to 20 carbon atoms, aryl groups having 6 to 20 carbon atoms, alkyl groups having 1 to 10 carbon atoms, alkenyl groups having 2 to 20 carbon atoms, alkynyl groups having 2 to 20 carbon atoms, aralkyl groups having 7 to 20 carbon atoms, halides, or
the radicals R1 are alkyl polyether groups —O—(R6—O),—R5 wherein R6 are identical or different and are branched or unbranched, saturated or unsaturated, aliphatic, aromatic or mixed aliphatic/aromatic bridging C1-C30 hydrocarbon groups, r is an integer from 1 to 30, and R5 are unsubstituted or substituted, branched or unbranched, terminal alkyl, alkenyl, aryl or aralkyl groups, or
two R1 form a cyclic dialkoxy group having 2 to 10 carbon atoms in which case 0 is <3,
or two or more silanes of formula I) can be bridged via radicals R1; and
wherein the radical R2 is selected from the group consisting of linear and branched alkylene groups having 1 to 20 carbon atoms, cycloalkyl groups having 4 to 12 carbon atoms, aryl groups having 6 to 20 carbon atoms, alkenyl groups having 2 to 20 carbon atoms, alkynyl groups having 2 to 20 carbon atoms and aralkyl groups having 7 to 20 carbon atoms; and wherein the group X is selected from the groups
—HNC(═O)—, —C(═O)NH—, —C(═O)O—, —OC(═O)—, —OC(═O)NH—,
—HNC(═O)O—, —R3NC(═O)NR3—, —R3NC(═NR3)NR3—, —R3NC(═S)NR3—, wherein the radicals R3 within the group X may be identical or different and are selected from a hydrogen atom or as defined for R2 under the condition that at least one R3 within the group X is a hydrogen atom; and wherein the groups A within a molecule may be identical or different from each other and are aromatic groups; and wherein the radicals R′ within a molecule may be identical or different and are selected from aromatic groups A and alkylene radicals having 1 to 20 carbon atoms, which may have cyclic, branched and/or aliphatically unsaturated groups; and
wherein G is a hydrogen atom or a —C(═O)—R8 group or a —SiR83; group, wherein R8 is selected from linear, branched and cyclic C1-C20-alkyl groups, C6-C20-aryl groups, C2-C20-alkenyl groups and C7-C20-aralkyl groups; and
wherein the groups Y within a molecule may be identical or different from each other and are selected from the groups
—HNC(═O)—, —C(═O)NH—, —C(═O)O—, —OC(═O)—, —OC(═O)NH—,
—HNC(═O)O—, —R4NC(═O)NR4—, —R4NC(═NR4)NR4—, —R4NC(═S)NR4—, wherein the radicals R4 within a group Y and within a molecule may be identical or different and are selected from a hydrogen atom or as defined for R2 under the condition that at least one R4 within each group Y is a hydrogen atom; and wherein m is an integer from 0 to 4, and wherein the silane may also be in the form of oligomers which are formed by hydrolysis and condensation of silanes of formula I).
