ABSTRACT:
A polymer comprising units having the formula (I)wherein: Q1comprises at least one aryl or heteroaryl group; Q2comprises at least one aryl or heteroaryl group; X1is O bonded directly to an aryl carbon of Q1; X2is O bonded directly to an aryl carbon of Q2; Z is a linker comprising at least one —(C(R2)2)— group; Y is a single bond or linker group (e.g., comprising up to about 50 carbons); R1is independently at each occurrence H, a halogen, an alkyl group, a heteroalkyl group, an aryl group, or a heteroaryl group; R2is independently at each occurrence H, an alkyl group, or a heteroalkyl group; and R3is H or a crosslinkable group.
