Benzocarborano[2,1- b:3,4- b ′]dithiophene containing conjugated polymers: Synthesis, characterization, and optoelectronic properties

Abstract

We report the stannylation of a benzocarborano[2,1-b:3,4-b′] dithiophene monomer and its polymerization by Stille polycondensation with solubilized cyclopentadithiophene and diketopyrrolopyrrole derivatives. The physical, material, and optoelectronic properties of the resultant conjugated copolymers are reported, demonstrating that benzocarboranodithiophene acts as a mildly electron-withdrawing monomer. © 2013 American Chemical Society.
