They self-assembled into thin membranes under high concentration and helical nanofibers under low concentration in pure water. Sol-gel transcription reactions were carried out under both acidic and basic conditions using the self-assemblies of these two gelators and the mixtures with CTAC as templates and TEOS as precursor. Under acidic conditions, minimum gel concentrations of L-18ValPyBr and D-18ValPyBr are very low. After sol-gel polymerization, a kind of cotton-like silica constructed by twisted mesoporous silica ribbons was obtained. These ribbons were 60 nm in width and 10 nm in thickness. Under basic conditions, both mesoporous twisted ribbons and nanotubes constructed by tightly coiled ribbons were obtained. Generally, left-handed helical structures were obtained by using L-18ValPyBr, while right-handed helical structures were obtained by using D-18ValPyBr. The morphologies were sensitive to the concentration of NH(3). When the concentration of NH(3) was 2.5 wt%, twisted ribbons were obtained. When the concentration of NH(3) was higher than 5.0 wt%, nanotubes constructed by tightly coiled ribbons were obtained. Mesoporous silica structures in nano- and micro-size were prepared by using the mixtures of L-18ValPyBr and CTAC under both acidic and basic conditions. Under acidic conditions, helical mesoporous fibers were obtained, and their diameter was increased with increasing the ratio of CTAC to gelator.
