| 英文摘要 | A copolymer of dendronized poly(p-phenylene vinylene) (ppv), poly{2-[3',5'-bis (2'-ethylhexyloxy) bnenzyloxyl]-1,4-phenylene vinylene}-co-poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (be-co-meh-ppv), was synthesized with the gilch route to improve the electroluminescence and photovoltaic properties of the dendronized ppv homopolymer. the polymer was characterized by ultraviolet-visible absorption spectroscopy, photoluminescence spectroscopy, and electrochemical cyclic voltammetry and compared with the homopolymers poly{2-[3', 5'-bis(2-ethylhexyloxy) benzyloxy-1,4-phenylene vinylene) (be-ppv) and poly[2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylene vinylene] (meh-ppv). polymer light-emitting diodes based on the polymers with the configuration of indium tin oxide (ito)/poly(3,4-ethylene dioxythiophene) : poly(styrene sulfonate) (pedot : pss)/polymer/ca/al were fabricated. the electroluminescence efficiency of be-co-meh-ppv reached 1.64 cd/a, which was much higher than that of be-ppv (0.68 cd/a) and a little higher than that of meh-ppv (1.59 cd/a). photovoltaic properties of the polymer were studied with the device configuration of ito/pedot : pss/polymer : [6,6j-phenyl-c-61-butyric acid methyl ester] (pcbm)/mg/al. the power conversion efficiency of the device based on the blend of be-co-meh-ppv and pcbm with a weight ratio of 1: 3 reached 1.41% under the illumination of air mass 1.5 (am1.5) (80 mw/cm(2)), and this was an improvement in comparison with 0.24% for be-ppv and 1.32% for meh-ppv under the same experimental conditions.
