Patent ID: 6908952

Claim:
A photoiniferter of the formula: wherein R 1 and R 2 are each independently selected from H, an alkyl group, a nitrile, a cycloalkyl group, a heterocyclic group, an arenyl group and an aryl group, or R 1 and R 2 taken together with the carbon to which they are attached form a carbocyclic ring; R 3 and R 4 are each independently selected from an alkyl group, a cycloalkyl group, an aryl group, a heterocyclic group, an arenyl group, or R 3 and R 4 taken together with the carbon to which they are attached form a carbocyclic ring; R 5 and R 6 are each independently selected from an alkyl group, a cycloalkyl group, a heterocyclic group, an aryl group, an arenyl group, or R 5 and R 6 taken together with the nitrogen to which they are attached form a heterocyclic ring; R 7 is an organic or inorganic moiety and has a valency of m; Z is —O—, —S—, or —NR 8 wherein R 8 can be a H, an alkyl, a cycloalkyl or aryl, a heterocyclic group, an arenyl, m is at least 1; Q is a linking group selected from a covalent bond, an aryl group, (—CH 2 —) o , —CO—O—(CH 2 ) o —, —CO—O—(CH 2 CH 2 O) o —, —CO—NR 8 —(CH 2 ) o —, —CO—S—(CH 2 ) o —, where o is 1 to 12, and R 8 is H, an alkyl group, a cycloalkyl group, an arenyl group, a heterocyclic group, or an aryl group; and n is 0 or 1.
