带4-烷氧基苯甲酸酯端基的三芳基吡啶香蕉型衍生物的合成与性能研究

摘要

Banana-shaped triarylpyridine derivatives with terminal 4-alkoxybenzoic ester chains were synthesized efficiently from pyrylium salt via three steps,their structures were determined by1H NMR,13C NMR and HR-Mass,such molecules are not mesogens which were investigated by POM and DSC,their UV-vis,PL spectroscopic properties were also studied.%从吡喃嗡盐出发仅经三步反应高效地合成了带4-烷氧基苯甲酸酯端基的三芳基吡啶香蕉型衍生物,并用1H NMR,13C NMR和HR-Mass对它们的结构进行了表征,用POM及DSC的方法研究了它们的相变行为,对其UV-vis、PL光谱性质也进行了分析.
