Abstract
The photooxidation reaction of bis-thiacarbocyanines based on 3,3'-dimethylthiacarbocyanine by viologens (methyl viologen, p-chlorophenyl viologen, p-cyanophenyl viologen) in acetonitrile, as well as their complexes with cucurbit[8]uril by monomeric complexes of viologens with cucurbit[8]uril in water was studied. The result of the photooxidation reaction of dye monomers in acetonitrile is the formation of the thiacarbocyanine dication-radical, bis-thiacarbocyanine trication-radicals and viologen cation-radicals. The consequence of photooxidation in water in the presence of cucurbit[8]uril is the formation of trication radicals of dye complexes and cation radicals of viologen complexes.
