Polymers for organic photovoltaics

Abstract:

A polymer comprising: ##STR00001## In this polymer R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 are independently selected from H, F, Cl, S, CN, or substituted, unsubstituted, straight-chain, branched, or cyclic alkyls ranging from 1 to 100 carbon atoms. The length of the polymer can range with n from about 1 to about 100,000 repeat units.
