A chirality indicator for the walls and the surfaces of silica nanotubes

单独螺旋状的硅石 nanotubes 根据文学过程被准备，用象模板的一双 chiral cationic low-molecular-weight gelators 的 self-assemblies。chirality 指示物， 4,4 二度(triethoxysilyl )-1,1-biphenyl, 被开发决定硅石 nanotubes 的 chirality。表面的 chirality 和硅石 nanotubes 的笨重的墙从 biphenylene 戒指的扭曲被理解。

Single-handed helical silica nanotubes were prepared according to the literature procedures,using the self-assemblies of a pair of chiral cationic low-molecular-weight gelators as the templates.A chirality indicator,4,4＇-bis（triethoxysilyl）-1,1＇-biphenyl,was developed to determine the chirality of the silica nanotubes.The chirality of the surfaces and the bulky walls of the silica nanotubes were understood from the twist of the biphenylene rings.
