Abstract
A polymer comprising In this polymer, R, R′, and R″ are independently selected from the group consisting of: H, Cl, F, CN, alkyl, alkoxy, alkylthio, ester, ketone and aryl groups. Additionally, in this polymer X and X′ are independently selected from aryl groups. Finally, m independently ranges from 1 to 100 and n independently ranges from 0 to 99.
