螺旋和不对称结构在自然界中广泛存在。由于其与生命过程有着密切的联系,引起了人们普遍关注。随着纳米技术的发展,在纳米尺度下,构建螺旋和不对称结构引起了科研人员的广泛兴趣。这类材料在不对称催化、对映体拆分、手性响应器件以及手性光学领域拥有重要的前景。本文仅限于本课题组的工作,介绍以手性两亲小分子的自组装体为外模板制备的单手螺旋聚倍半硅氧烷纳米纤维和纳米管,包括:其形成机理、结构表征以及在对映体拆分中的应用。
Spiral and asymmetric structures are widespread in nature. Because of its close relationship with the life process, it has aroused widespread concern. With the development of nanotechnology, at the nanoscale, the construction of spiral and asymmetric structure has aroused widespread interest of researchers. Such materials have important prospects in the fields of asymmetric catalysis, enantiomeric resolution, chiral response devices, and chiral optics. This article is limited to the work of our group to introduce single-handed helical polysilsesquioxane nanofibers and nanotubes prepared by self-assembly of chiral amphiphilic small molecules, including their formation mechanism, structural characterization and Application in enantiomeric resolution.
