Abstract: Five novel asymmetric D–A–A′-type small molecules (SMs) consisting of a triphenylamine (TPA)-diketopyrrolopyrrole (DPP)/5,6-difluoro-2,1,3-benzothiadiazole (BT) conjugated backbone with different terminal groups were designed and synthesized successfully. First, the ethynyl-functionalized thiophene was introduced to BT-based SMs with… read more here.
