Abstract
Provided are novel polymerizable monomers allowing preparation of exceptionally useful surface coatings by polymerization. Embodiments include highly reticulated chiral nanoparticles useful, for example, for covalently grating biological ligands, epitaxial growth of conductive polymers onto surface modified indium tin oxide (ITO) electrodes and arrays of gold nanodots and electroconductive polymers.
Claims39
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)—(CH2)n3—(Y0)p—]—(Z)—m[(Y0)p—(CH2) n3—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;
- Y0 represents a divalent radical which links the center of said C2-C6 symmetric or pseudo-symmetric monomer to the (CH2)—n3 chain;
- p is an integer selected from 0 or 1;
- n3 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.
