【摘要】 本文通过对称内炔和叠氮的无催化剂参与点击化学成功合成了1,2,3-三唑热致性液晶,并在均相混合溶剂中与氯化钯加热回流反应制备了其淡黄色的氯化钯配合物。通过偏光显微镜和差示扫描量热法测试,两个化合物均具有液晶性,呈现典型的扇形层状液晶织构。相对于1,2,3-三唑点击配体,弱的Pd-N配位键连接的氯化钯配合物有相对较差的热稳定性,窄的介晶性温度范围,较高的熔点和清亮点。扫描隧道显微镜观测表明,1,2,3-三唑点击配体可在定向的石墨基材表面上自组装成条带状的纳米结构。更多还原

【Abstract】 A 1,2,3-triazole linked thermotropic liquid crystal was successful synthesized through internal alkyne and azide catalyst-free click reaction and its palladium complex also was facile prepared by heated refluxing click product and palladium chloride in a homogeneous mixed solvent. Both the compounds show a typical fan-shaped texture of lamellar mesophase. Furthermore, 1,2,3-triazole "click" ligand can self-assemble into strips-shaped nanostructures on the oriented graphite substrate surface. Wherein palladium complex has a higher melting and clearing point, narrower mesomorphic temperature range and relatively poorer thermal stability due to weak Pd-N coordination bond connections as compared with its uncoordinated ligand.更多还原
