钯过渡金属配合物的合成,表征及纳米胶束自组装

Self-assemly of Nano-micelle of Coordination Compound of Transition Pd Metal Ion

以水杨醛和邻氨基苯酚为原料来制备希夫碱,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,在水和乙醇混合反应体系中与Pd(Ⅱ)过渡金属通过自组装形成配合物。透射电镜形态观测到10～20nm左右的线状形态的纳米胶束。并利用红外光谱,紫外可见吸收光谱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 pyrdine-4-carboxylate which was further treated with palladium(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 10-20nm of column morphology observed by TEM was formed.The structure and properties of the complex were characterized by IR and UV.
