Claim:
An optical active polymerizable monomer containing at least two oxidizable groups and at least two chiral centers of the general formula: q [A—C*—(═O)(X)—(CH 2 ) n 3 —(Y 0 ) p —]—(Z)— m [(Y 0 ) p —(CH 2 ) n 3 —C(═O)(X)—C*—B] wherein, —C(═O)(X) represents an activated carboxyl group capable of binding a functional group or a ligand; wherein such binding may occur pre- or post- (co)polymerization process, and when —C(═O)(X) represents a free carboxylic group also a salt of such a free carboxylic group; X represents a moiety of a molecule capable of reacting with a nucleophile group; A and B are the same or different oxidizable group; Z represents a two- to six-valence center, resulting in a C2-C6 symmetric or pseudo-symmetric monomer; Y 0 represents a divalent radical which links the center of said C2-C6 symmetric or pseudo-symmetric monomer to the (CH 2 )—n 3 chain; p is an integer selected from 0 or 1; n 3 is an integer from 0-100; q and m each represents an integer from 1-5; provided that the sum of q +m is an integer from 2 to 6; and wherein the sign * signifies that an associated carbon atom is an active optical center.
