Chiral photochemistry appears to be a highly challenging topic and still very much in its infancy, especially if comparing to its well-developed thermochemical counterpart.Significant efforts have been devoted in order to improve stereoselectivity of chiral photoreactions,among which,the supramolecular strategy proven the most promising.The present review,motivated by the rapid progress in the supramolecular chiral photochemistry,concentrates on advancements achieved mainly in the last decade.The features and advantages of supramolecular chiral photochemistry are exemplified by representative photoreactions in terms of the chiral hosts/assemblies.
