摘要
利用后重氮偶合方法制备了2种含咔唑双功能生色团的三聚磷腈,并用1H NMR、31P NMR、IR、UV-V is以及DSC等测试技术对磷腈小分子的结构进行了分析和表征。31P NMR谱图上的单峰说明,六氯环三磷腈上的氯已经全部被咔唑基团取代。1H NMR、IR、UV-V is谱图表明,对硝基偶氮苯基团以不同比例连接在咔唑环上。DSC结果显示,磷腈小分子为完全无定型态,玻璃化转变温度随着生色团含量的增加而升高。
Two cyclotriphosphazenes containing carbazole chromophores were prepared via a post-azo-coupling reaction. These two molecules were characterized by using ^1H NMR, ^31P NMR, IR, UV-Vis and DSC. The single resonance in the ^31p NMR spectra of compounds 3 - 5 show that the chloro-groups on the cyclotriphosphazene was completely substituted by the carbazolyl group. Results of ^1H NMR, IR and UV-Vis demonstrate that the azo group was linked to the 3-position of the carbazole ring with different contents. DSC measurement results indicate that these molecules are amorphous in nature and the glass transition temperature increases with increasing the content of chromophores.
