摘要
在氮气或空气气氛中,利用CuB r催化的点击化学反应合成了新型单取代的二茂铁液晶化合物—含1,4-取代的1,2,3-三唑系列3a~3e和5-溴-1,4-取代的1,2,3-三唑系列4b~4e。通过NMR、FT-IR、HRMS测试验证了其分子结构的正确性。DSC、POM测试表明两个系列化合物均呈现典型的丝状向列相液晶织构,极性三唑环5位上溴取代系列化合物4比相应的未取代系列3具有更宽的介晶性温度范围。但TGA测试表明,4系列化合物的热稳定性比3系列化合物差。循环伏安法测试两系列化合物均展示准可逆的单电子氧化还原进程。
New mono-substituted ferrocene-containing liquid crystals with 1,4-substituted-1,2,3-triazole series 3a~3e and 5-bromo-1,4-substituted-1,2,3-triazole series 4b ~ 4e were successful synthesized by using CuBr catalyzed click reaction in an nitrogen or air atmosphere. Two series of compounds showed a typical nematic liquid crystal texture, and 5-bromo-1,4-substituted-1,2,3-triazole series 4 had a wider mesophase temperature range than the corresponding series 3. But the thermal stability of the series 4 is worse than the series 3. The cyclic voltammetry investigations revealed that redox-active ferrocenyl groups of 3 and 4 exhibited one-electron transfer processes.
