摘　　要：以异烟酸和溴代十二烷为原料合成液晶基元异烟酸十二烷基酯,在水和无水乙醇混合反应体系中,室温下分别与Pd(Ⅱ)、Cu(Ⅱ)和Ni(Ⅱ)过渡金属按4∶1的摩尔比混合反应,通过自组装形成配合物。透射电镜形态观测表明,配合物之间借助超分子力和配体的液晶性协同作用构建成25～40nm左右的棒状形态的纳米胶束。并利用红外光谱,紫外可见吸收光谱,荧光光谱等手段对其结构和性质进行了表征。Pyridine-4-carboxylic acid reacted with dodecyl bromide to give liquid crystal unit dodecyl pyridine-4-carboxylate which was further treated with palladium(Ⅱ) ion,copper(Ⅱ) ion or nickel(Ⅱ) ion in mole ratio 4∶1 to form the coordination compound at room temperature in the mixed reaction system of water and ethanol.The nano-micelle which was 25～40 nm of column morphology observed by TEM was formed by cooperation effect of supramolecule force and liquid crystal capability.The structure and properties of the complex were characterized by IR,UV and fluorescence spectra.
