The present invention relates to compounds and silicic acid (hetero)polycondensates comprising structures of formulas (1) and/or (2),
R2 is a hydroxy group or a free carboxylic acid residue or a carboxylic acid ester derived therefrom or a salt derived therefrom,
R3 denotes a residue having a hydrocarbon-containing branched or unbranched backbone which is bonded to silicon by carbon, and can be arbitrarily interrupted by heteroatoms or coupling groups or by other heteroatom-containing groups, where the zigzag line purely schematically denotes the hydrocarbon-containing backbone,
the three not more closely characterized bonds of the Si-atom represent additional residues bonded to the silicon atom, selected from residues that can be hydrolyzed from silicon, hydroxy groups and residues bonded to silicon by carbon which can have the same meaning as R3 or can have a different meaning deviating therefrom, or represent oxygen bridges to further silicon atoms and/or other metal atoms in the case the structure (1) is part of a silicic acid (hetero)polycondensate,
the residue Y is either divalent, and then has the meaning of —S—, —NR4— or —P(O)(R4)c(Z′)d— with Z′═OR4, c=0 or 1, d=0 or 1 and (c+d)=1, or trivalent and has the meaning of —N═ or —P(O)═,
R4 represents a hydrocarbon-containing residue and in the —NR4— residue can in addition have the meaning of hydrogen,
W is a substituted or unsubstituted hydrocarbon residue bonded to Y, the chain of which can be interrupted by —S—, —O—, —NH—, —NR4—, —C(O)O—, —NHC(O)—, —C(O)NH—, —NHC(O)O—, —C(O)NHC(O)—, —NHC(O)NH—, —S(O)—, —C(S)O—, —C(S)NH—, —NHC(S)—, —NHC(S)O—,
Ar is a residue that carries at least one aromatic group which is unsubstituted or substituted with one or more residues, where the aromatic groups do not carry substituents, selected from boronic acid-, the carboxylic acid-, the phosphine acid-, the phosphonic acid- and the sulfonic acid group and from hydroxy groups,
where Ar must be bonded to W if a≠0,
Z is selected from urethane-, acid amide-, ether- and ester groups,
R1 is a straight chain or branched, organically polymerizable group carrying at least one C═C double bond, and the index e is 1, 2, 3, 4 or an integer greater than 4,
the index a is equal to 0 or 1 or 2,
the index b=1, 2, 3 or an integer greater than 3 if a≠0, and b=1 or 2 if a=1,
the index m is 1, 2 or an integer greater than 2,
the index n is 0, 1, 2 or greater than 2 and
the index o is 1 or 2 or greater than 2.
composites and organically polymerized masses produced therefrom and methods for producing the same.
