To obtain a dual-functional polymeric semiconductor for efficient red-light emission and high-performance photovoltaic cells, an alternating copolymer containing triphenylamine (TPA; as donors) and cyano-substituted phenylene (as acceptors), TPA-CNPPV, was synthesized by Wittig reaction. The polymer was characterized by FT-IR, 1 H-NMR, thermogravimetric analysis (TGA) and differential scanning...
A novel kind of hyperbranched conjugated light emitting polymers with 2,5-dimethyloxyl substituted phenylene vinylene as the connecting units and different hole or electron transporting groups such as dimethylaniline phenylene or pyridyl phenylene as the terminal groups were synthesized by modified one step Wittig polymerization reaction. The photophysical properties in solution and in films of hyperbranched...
