多功能聚炔的控制制备及热性能

提出一种多功能聚炔的制备新方法——点击化学制备法。有效地实现了多功能基团取代聚炔的制备,使用红外光谱(FT-IR)、核磁共振(1H-NMR)以及热重分析(TGA)对制得的高分子结构和热性能进行了详细表征,研究结果发现,该方法不仅制备条件温和,操作简单,而且产率高;同时芳基口恶唑基团的引入,有效地将电子传输和非线性吸收功能基团有效构筑于同一聚炔高分子中,实现多功能性,而且合成的高分子呈现高的热稳定性,热分解温度高达372.9℃。

Controllable Preparation and Thermal Properties of Multifunctional Polyacetylene

A kind of new method,"click" chemistry,is applied to preparation of the multifuntional polyacetylene by molecular design.The multifunctional polyacetylene was effectively obtained by "click" chemistry method.Its molecular structures and thermal property were characterized and evaluated by FT-IR,1H-NMR and TGA,respectively.The results show that the method possesses mild preparation condition and simple process,and also high yield.Simultaneously,the incorporation of aryl oxadiazole group into polyacetylene(P1) effectively achieves the architecture of connecting the electron-transporting group and nonlinear optical absorbance group together into resulting multifunctional polyacetylene.The resultant polymer also shows high thermostability and its decomposition temperature rises up to 372.9 ℃.
