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°C.
