Chiral phenomena are common in living systems. Despite the fact that development of materials has often been inspired by chemistry from the biological world, materials that take advantage of inherent chirality have found relatively few applications. It is therefore probable that much remains to be gained from novel applications of molecular, macromolecular and supramolecular chirality. Among the most intriguing recent advances in studies of chiral materials is the development of mechanisms to control the shape and properties of chiral molecules. Photo-induced helical chirality inversions have been studied for several years and significant achievements have been reported. Recently, electronically triggered systems have drawn significant attention. These technologies offer the potential for development of novel materials that take advantage of photonic or electronic modulation of molecular recognition, optical or mechanical properties.
