摘　　要：用L-苯甘氨酸合成了L-苯甘氨酸衍生物阳离子两亲化合物,以其自组装体为模板,采用四乙氧基硅烷为硅源,制备了介孔SiO_2空心球.结果表明,制备的介孔SiO_2纳米粒子直径50~200nm,孔径3.8nm左右,孔道成平行排列.Silica hollow nanospheres were prepared through a sol-gel transcription method using the self-assemblies of L-phenylglycine derivatives derived fromL-phenylglycine as the templates and tetraethoxysilane as the precursor.It was found that the as-synthesized silica hollow nanospheres had a diameter about 50-200 nm.The diameter of the pore channels was about3.8nm in the shell.The pores were closely spaced and parallel to each other.
