摘　　要：依照文献以L-苯甘氨酸为手性源合成了一个手性阴离子两亲小分子化合物.利用圆二色谱表征了该化合物水中的自组装行为.通过溶胶-凝胶复制法,以该手性两亲小分子化合物和结构助剂的组装体为模板制备了右手螺旋有机-无机杂化氧化硅纳米管.圆二色谱表征结果表明,4,4′-亚联苯基氧化硅中的联苯基团呈手性堆积.A chiral amphiphilic compound derived from L-phenyl glycine was synthesized according to the literature.The self-assembly behaviour in deionized water was studied using circular dichrosim（CD）.A series of right-handed twisted organic-inorganic hybrid silica nanotubes were prepared using this amphiphilic compound and a co-structure-directing agent through a sol-gel transcription method.The CD spectra of the 4,4′-biphenyl-silica nanotubes indicated that the aromatic rings stacked in chiral within the walls of nanotubes.
