【摘要】 本论文从分子设计思想出发，应用化学合成方法和过渡金属—有机配体自组装合成方法，合成了由刚性结构和柔性结构构成的液晶基元，应用疏溶剂作用和芳香基团π-π堆积等非共价键超分子力的协同作用构建成纳米柱胶束。 本论文首先合成由偶氮苯和十二烷基构建的具有表面活性的液晶基元，借助磺酸基和金属离子的垂直整理作用以及芳香基团π-π堆积协同作用在环己烷溶剂中构成稳定的纳米柱胶束，并应用过渡金属-有机配体自组装合成方法，合成了由异烟酸酯配体和过渡金属离子Pd(Ⅱ)、Cu(Ⅱ)和Ni(Ⅱ)配位合成了盘状液晶基元，借助疏溶剂作用和金属离子对π电子的弱配位作用、芳香基团π-π堆积的协同作用，在环己烷溶剂中构成稳定的纳米柱胶束。在此基础上，应用合成的具有三齿螯合配位结构特征的Schiff碱参与过渡金属和异烟酸酯配位组装，研究其对纳米柱胶束形态的调控作用。通过元素分析、红外光谱分析、紫外—可见光谱分析、荧光光谱分析和差热—热重分析等手段对化合物的结构和物理化学性质进行了表征，通过TEM观测到形态规则、均匀，尺寸大小在10nm-60nm左右的纳米柱和纳米线。本研究对今后对纳米材料自组装制备方面的进一步研究，以及纳米材料的进一步应用提供了理论和实验依据。更多还原

【Abstract】 In this paper,liquid crystal unit consisted by rigid and flexible structure was prepared based on the methods of chemical synthesis and self-assembly with transition metal ions and organical ligands in the view of molecular design.Nanorod-micelle was formed by hydrophobic effect and - stack in the relevant solvent.In the first place,the surfactantal liquid crystal unit composed by azo-benzene and dodecyl was synthesized.The steady nanorod-micelle was formed by upright-neaten effect of sulfonated group and - stack in the cyclohexane.In the second place,me disc-like liquid crystal unit was prepared with 4-carboxylpyridine dodecylester as liquid cystal ligand coordinated with transition metal ions(Pd(II) , Cu(II), Ni(II)). The steady nanorod micelle was formed by hydrophobic effect, weak coordination effect to which metal ions reacted eletron and - stack in the cyclohexane.Finally,the Schiff base was choosed as ligand to study the adjustive function to the morphology of nanorod micelle above.The structure of the synthesized complexes is characterized by element analysis ,FTIR,UV, fluorescence spectra and TG-DTA. The self-assembled nanorod morphologywith the size of 10nm-60nm is observed by TEM.The study would be expected to take on some referenced value to the study of preparation of nano-materials and new application of nano-materials for the future.更多还原
