摘要: 以D-缬氨酸为手性源合成了手性阴离子两亲性小分子化合物D-C12ValC10COONa. 用圆二色谱表征了该化合物在溶液和胶体中的自组装行为. 通过溶胶\|凝胶复制法, 以该手性化合物和结构助剂3-(三甲氧基硅基)丙胺的组装体为模板, 制备了左手螺旋1,2-亚乙基氧化硅纳米管. 扫描电镜和透射电子显微镜研究显示, 调节溶液浓度和pH值可以控制1,2-亚乙基氧化硅纳米管的手性, 而温度和溶剂配比的改变对纳米管手性并无影响.

Abstract: A chiral anionic amphiphilic compound derived from D-valine was synthesized. The self-assembly behavior of this compound in solution and in gel was studied using circular dichroism. Helical 1,2-ethylene-silica nanotubes were obtained through a sol-gel transcription method using the assembly of this chiral compound as template and a co-structure-directing agent, 3-aminopropyltrimethoxysilane. It was found that the handedness of 1,2-ethylene-silica nanotubes can be controlled by tuning the concentration and pH value of the reaction mixture. However, the reaction temperature and water/ethanol volume ratio in the reaction mixture did not affect the handedness of the nanotubes.

Key words: Self-assembly, 1,2-Ethylene-silica, Nanotube, Handedness inversion
