Compositions and applications of a multi-component benzo[1,2-B:4,5-B] dithiophene-thienothiophene randomly substituted polymers for organic solar cells
A polymer having at least four different repeat units comprising:In this polymer R1, R2, R3 and R4 can be independently selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof and where the combination of R1, R2, R3 and R4 are not all identical. Additionally, in this polymer, m, n, o and p can be greater than 1. x and y are different from each other and can be independently selected from the group consisting of: of alkyl group, alkoxy group, aryl groups,where y=1-3,where y=0-12,where R5 is selected from the group consisting of H, of alkyl group, alkoxy group, aryl groups,where R6 is selected from the group consisting of H, alkyl, substituted alkyls, aryls and substituted aryls,where R7 and R8 are independently selected from the group consisting of H, of alkyl group, alkoxy group, aryl groups, —NR9R10 where R9 and R10 are independently selected from the group consisting of H, of alkyl group, alkoxy group, aryl groups.
