英文摘要	In this study, the optical, electrochemical, electrolumiscent, and photovoltaic properties of a series of poly(p-phenylene vinylene) (PPV) derivatives bearing different dendritic pendants, poly{2-[3',5'-bis(2 ''-ethylhexyloxy)benzyloxy]-1,4-phenylenevinylene} (BE-PPV), poly{2-[2',5'-bis(3 '',7 ''-dimethyl)octyloxy]-1,4-phenylenevinylene} (BD-PPV), poly[2-methoxy- 5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV), poly{2-[3',5'-bis(2 ''-ethylhexyloxy)benzyloxy]-1,4-phenylenevinylene}-co-poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene] (BE-co-MEH-PPV), and poly{2-[2', 5'-bis(3 '',7 ''-dimethyl)octyloxy]-1,4-phenylenevinylene}-co-poly[2-methoxy-5-(3',7'- dimethyloctyloxy)-1,4-phenylenevinylene] (BD-co-MDMO-PPV), were investigated. The steric pendants strongly affect the absorption spectra, photoluminescence (PL) sepctra, the onset oxidation/reduction potentials, and further affect the electrolumiscent and photovoltaic properties. Copolymerization can reduce the steric effect and improve the electrolumiscent and photovoltaic properties. The brightness of light-emitting diodes base on copolymer BE-co-MEH-PPV and BD-co-MDMO-PPV reached 3988 and 3864 cd/m(2), respectively, much higher than that based on homopolymer BE-PPV (523 cd/m(2)) and BD-PPV (333 cd/m(2)), also higher than that based on MEH-PPV (3788 cd/m(2)). The power conversion efficiency (PCE) of solar cells based on BE-co-MEH-PPV and BD-co-MDMO-PPV reached 1.41, 0.76%, respectively, much higher than that based on BE-PPV (0.24%) and BD-PPV (0.14%).
