摘要
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,通过元素分析、红外光谱分析、紫外可见光谱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,直径在20nm^40nm左右的纳米柱。该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。
In the fast, 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 π-π stack in cyclohexane. The synthesized compound was characterized by element analysis, FT-IR and UV-Vis spectroscopy. The self-assembled nanorod morphology with the diameter of 20-40 nm was observed by TEM. The study would be expected to take on some reference values to the study of preparation of nano-materials and new application of nano-materials for the future.
