Claims20
A polymer of Formula (I):
- wherein R1, R′1, R2 and R′2 are each selected independently from the group consisting of hydrogen, alkyl (linear or branched), substituted alkyl, aryl, substituted aryl groups, and combinations thereof;
- R3 is an alkene, alkyne, or an unsubstituted aryl group or substituted aryl group that contains from about 2 to 36 carbon atoms, or a heteroaryl group containing from about 2 to 30 carbon atoms and may be optionally substituted;
- Ar1 and Ar2 are each independently an unsubstituted aryl group or substituted aryl group that each contains from about 6 to about 36 carbon atoms, or a heteroaryl group containing from about 2 to 30 carbon atoms and may be optionally substituted;
- a, b, and c are each independently 0, 1, 2, 3, 4, or 5;
- and
- n is the number of repeat units from about 2 to about 5000.
