Process of producing and applications of three component benzo1,2-B:4,5-B dithiophene-thienothiophene randomly substituted polymers for organic solar cells

摘要

A process of polymerizing; f with; wherein the stoichiometric ratio of f≈(g+h) and f, g and h are not equal to 0.;This process can also have R1 selected from the group consisting of alkyl group, alkoxy group, aryl groups and combinations thereof. Additionally, x and y can be different from each other and can be independently selected from the group consisting of: alkyl group, alkoxy group, aryl groups,; where y=1-3,; where y=0-12,; where R2 is selected from the group consisting of H, alkyl group, alkoxy group, aryl groups,; where R3 is selected from the group consisting of H, alkyl group, alkoxy group, aryl groups,; where R4 and R5 are independently selected from the group consisting of H, alkyl group, alkoxy group, aryl groups, —NR₆R₇ where R6 and R7 are independently selected from the group consisting of H, alkyl group, alkoxy group, aryl groups.
