CONJUGATED POLYMERS CONTAINING ALKYL AND ALKYL ESTER SIDE CHAINS

摘要

The present invention is a conjugated polymer that contains both Unit (I) and Unit (II) is shown below: X, in each occurrence, is independently selected from S or Se. M₁ and M₂ are independently selected from H or F. R₁ and R₂ are independently selected from straight-chain, branched or cyclic alkyl groups with 1-40 C atoms. The number ratio of Unit (I) and Unit (II) in the polymer chain ranges from 9: 1 to 1 :9.
