摘要 　通过后重氮偶合方法制备了一系列不同生色团含量的咔唑类双功能光折变聚合物,并用IR、1H NMR、UV vis、DSC以及GPC等对聚合物进行了分析和表征。IR和UV vis谱图显示偶氮苯基团已接到咔唑环上。UV vis结果表明:反应时间对该反应的影响非常大,当反应时间从6h增加到60h时,聚合物中生色团的含量从13.5%升高到66.7%。GPC结果显示后重氮偶合法比常规方法得到的该类聚合物的分子量明显提高。DSC结果显示聚合物的玻璃化转变温度随偶氮苯含量的增加而升高。 A series of carbazolebased bifunctional photorefractive polymers containing different azo group were prepared via a post azo coupling reaction. The structure of these polymers was characterized by IR, 1HNMR, UVvis, DSC and GPC. The results of IR and 1HNMR demonstrated that azo group had been substituted to the polymer. Reaction time affected the content of azobenzene chromophore. From the UVvis spectrum, it could be seen that the content of azo group raised from 13.9% to 66.7% when the time changed from 6 h to 60 h. The results of GPC showed that the molecular weight of these polymers was higher than that of the polymers obtained by common method. From DSC curves, it could be seen that the glass transition temperature Tg of the polymers raised with increasing the content of azo group.
