Abstract: Molecular conformation has a striking function in dominating the molecular orientation, crystallinity, charge mobility, film morphology, and photovoltaic performance for classic donor−π–acceptor (D−π–A) type copolymers. Herein, we systematically investigate this correlation by modulating the chemical… read more here.
