Summary:The review is devoted to the structure and photoprocesses in dimers of polymethine dyes and their complexes as objects of supramolecular photochemistry. The results of studies on the structure of dimers and dimeric complexes with cucurbiturils obtained from quantum chemical calculations are presented. The spectral-luminescent properties of dimers and approaches to their origin are considered. Data on the triplet states of dimers and dimeric complexes are presented. The results of studies on triplet-triplet energy transfer, electron phototransfer in redox reactions of dimers, and photosensitized oxidation reaction are analyzed.
