Influence of synthetic pathway, molecular weight and side chains on properties of indacenodithiophene-benzothiadiazole copolymers made by direct arylation polycondensation

Abstract

Poly(indacenodithiophene-<italic>alt</italic>-benzothiadiazole) with different side chains and molecular weight is made using two different pathways in which all C–C coupling steps are achieved by C–H activation, and the products are comprehensively investigated.
