In the present paper, supramolecular chiral photoreactions using cyclodextrins (CDs) as chiral inductors, including monomolecular photochirogenic reactions, bimolecular photochirogenic reactions, photochemical catalysis as well as the wavelength effects in photochirogenesis, have been summarized. This review focused on the binding behavior of CDs with different photosubstrates, the characteristics of chiral photoreactions mediated by CDs, the products distribution and stereoselectivity of chiral photoreactions with CDs and their working mechanisms. This paper concluded the advantages of CDs as host molecules used for chiral photoreactions, the problems existing in these supramolecular photochirogenesis systems and the perspective in this multidisciplinary research field.
