从二种 chiral 分子,有一个不对称的碳原子的 R-di-2-naphthylprolinol (DNP ) 和有 conformational 不对称现象的 R-(+)-1,1'-bi-2-naphthol dimethyl 醚(BNDE ) 的器官的 nanotubes,被沉浸的技术作为模板用多孔的氧化铝膜准备。从有一个不对称的碳原子的 DNP 的 nanotubes 在 nanotubes 的形成之上与 CD 信号的细微红移动介绍了象解决方案的一样的 chirality,这被发现,当没有明确的 chirality 能与 conformational 不对称现象从 BNDE 为 nanotubes 被识别时。
Organic nanotubes from two kinds of chiral molecules, R-di-2-naphthylprolinol (DNP) with an asymmetric carbon atom and R-(+)-1,1'-bi-2-naphthol dimethyl ether (BNDE) with the conformational asymmetry, were prepared by the immersing technique using porous alumina membranes as the template. It was found that the nanotubes from DNP with an asymmetric carbon atom presented the same chirality as the solution with slight red shift of the CD signals upon the formation of the nanotubes, while no well-defined chirality could be identified for the nanotubes from BNDE with the conformational asymmetry.
