| 摘 要： | 利用Suzuki缩聚反应,合成了以1,3,6,8-(N-己基)咔唑为核的新型超支化聚对苯撑共聚物.用红外、核磁共振对聚合物的结构进行测定,表明咔唑以及吡啶单元成功引入聚合物中.聚合物可溶于四氢呋喃、氯仿和甲苯等有机溶剂.用凝胶渗透色谱法测得超支化聚合物的分子量在40000～110000之间,分子量随着1,3,6,8-(N-已基)咔唑含量的增加逐渐增加.超支化聚合物在溶液和薄膜状态下的吸收峰分别位于315～334nm和402～410nm之间.随着支化咔唑单元含量的增加,超支化聚合物的吸收峰均发生一定程度的蓝移.超支化聚合物在溶液和薄膜状态下的最大发射峰分别位于402～410nm和402～415nm之间,并且随着引入的支化咔唑单元含量的增加,分子内发生更加有效的分子内电荷转移,PL光谱发生略微的红移.

| Abstract: | A serials of hyperbranched poly(para-phenylene) incorporating a new 1,3,6,8-tetrabromo-9-hexyl-carbazole were prepared by Suzuki polycondensation.The polymers were identified by fourier transform infrared spectroscopy(FT-IR) and nuclear magnetic resonance(NMR).All polymers were soluble in common organic solvents,such as tetrahydrofuran,chloroform and toluene.Gel permeation chromatography(GPC) showed the Mn of hyperbranched polymers varied from 40000 to 120000,and Mn increased with the rising content of 1,3,... |
