Abstract: | The results of studying optical and photochemical properties of organic supramolecular nanostructures capable of self-organizing due to specific intermolecular interactions are generalized in the review. The linear and nonlnear optical properties of supramolecular nanostructures of the guest—host type based on cyclodextrins, intramolecular and intermolecular complexes of crown-containing styryl dyes with metal cations, and aggregates of carbocyanine dyes are described. Photolysis reactions in supramolecular nanostructures, including photoisomerization, photocycloaddition, and formation of excimeric and charge-transfer complexes are presented. A possibility of controlling photochemical transformations in these systems by the light and cations of metal salts is shown. |
