Supramolecular organic photochemistry: control of covalent bond formation through noncovalent supramolecular interactions and magnetic effects.

Abstract

Supramolecular organic photochemistry, a field concerned with the interaction of light with supramolecular assemblies of organic molecules, has been inspired by the remarkable structural and dynamic features of guest@host chemistry, particularly as exemplified by enzymes. Exemplars of supramolecular organic photochemistry from soft-matter hosts (micelles) and hard-matter hosts (porous solids) are discussed with an emphasis on how noncovalent interactions, which are at the heart of supramolecular chemistry, can be systematically exploited to control the catalytic and magnetic effects on the formation of covalent bonds from photochemically produced pairs of radicals.
