A chiral ordered mesoporous crystal was synthesized using the chiral surfactant. The material has a twisted hexagonal rod-like morphology. Transmission electron microscopy combined with computer simulations confirm the presence of hexagonally ordered chiral channels winding around the central axis of the rods. The helicity and the morphology of the mesoporous silica are controlled by the stirring rate during the chiral surfactant self-assembly. A racemic chiral mesoporous silica has been synthesized by using achiral surfactant. Furthermore, right- and left-handed excess chiral mesoporous silica nanotubes with helical channel in the wall have been formed in the presence of chiral molecules.
