Process of producing and applications of three component benzo[1,2-b:4,5-b] dithiophene-thienothiophene randomly substituted polymers for organic solar cells

Abstract

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, —NRRwhere R6 and R7 are independently selected from the group consisting of H, alkyl group, alkoxy group, aryl groups.
