合成并表征了一种新型的以苯为核、对苯乙炔为连接基、二甲氨基苯为端基的超支化共轭聚合物（DMA-HPV）。它显示出优异的溶解性、成膜能力和非常高的热稳定性（Tg = 255°C，TID = 398°C）。薄膜中的荧光量子效率几乎与溶液中的荧光量子效率相当（约50%）。制作了发光二极管和发光单元。版权所有© 2004约翰威利父子有限公司
A novel hyperbranched conjugated polymer with benzene as core, phenylene vinylene as connecting groups and dimethylamino benzene as end groups (DMA-HPV) was synthesized and characterized. It shows excellent solubility, film-forming ability and very high thermal stability Tg = 255°C, TID = 398°C). Its fluorescence quantum efficiency in film is almost as large as that in solution (∼50%). The light emitting diodes and the light emitting cells were fabricated.
