Recently organic semiconductors have been developed for solar cell application because of their advantages such as light weight, low cost, flexibility and easy processing and manipulation. In this work, a new donor-acceptor conjugated copolymer containing dialkoxinaphthalene was synthesized via Suzuki coupling reaction. Donor-acceptor copolymer improve the visible absorption and decrease HOMO energy level of the conjugated polymer. The copolymer was characterized by elemental analysis, 1H-NMR, 13C-NMR, FT-IR, UV absorption, photoluminescence (PL), and cyclicvoltammetry (CV). The themal property of this material was confirmed by using the thermogravimertric analysis (TGA) and differential scanning calorimeter (DSC). |
