제목 Synthesis of donor-acceptor copolymer for efficient Organic Photovoltaic Devices.
초록 In recent studies, polymers based on a TPD unit have presented a relatively low band gap, which is related to their effective optical absorption, good hole mobility, and well-arranged energy level for efficient charge transport. We synthesized donor-acceptor copolymer, which is composed of phenanthro[1,10,9,8-cdefg]carbazole as the donor unit and a TPD unit as the acceptor. The copolymer appear the well-separated distribution of the HOMO and LUMO levels and relatively low band-gap (1.6 eV) by its internal charge-transfer, which accord with the results of density functional theory (DFT) calculation for the distribution of HOMO and LUMO levels.
