Abstract
The synthesis of highly ordered chiral periodic mesoporous organosilica (PMO) materials is described using a novel approach. Chiral dopants featuring removable chirality combined with freely rotating bulk monomers, resulting in a bulk chiral material with handedness related to the chiral dopant. Once incorporated into the solid-state PMO, removal of a chiral-linker in the dopant is readily accomplished, and occurs with complete preservation of the CD signal in the material. In the monomeric form, this would lead to total loss of chirality. The chirality of the material is retained even after prolonged hydrothermal treatment indicating remarkable, stable chirality transfer within the walls of PMO solid.
