Abstract

Abstract: A chiral anionic amphiphilic compound derived from D-valine was synthesized. The self-assembly behavior of this compound in solution and in gel was studied using circular dichroism. Helical 1,2-ethylene-silica nanotubes were obtained through a sol-gel transcription method using the assembly of this chiral compound as template and a co-structure-directing agent, 3-aminopropyltrimethoxysilane. It was found that the handedness of 1,2-ethylene-silica nanotubes can be controlled by tuning the concentration and pH value of the reaction mixture. However, the reaction temperature and water/ethanol volume ratio in the reaction mixture did not affect the handedness of the nanotubes.

Key words: Self-assembly, 1,2-Ethylene-silica, Nanotube, Handedness inversion
