Abstract

Abstract Novel p-type and low bandgap functional dendritic oligothiophenes bearing hole- transporting carbazole as peripheral substituents and an electron-withdrawing dicyanovinyl core group, namely, DCT (n)-DCN, where n= 1 or 2 for solution-processable photovoltaic (PV) applications have been synthesized. With electron-donating carbazole surface- functionalized moieties conjugated with dicyanovinyl core group, the optical bandgap of ...
