Abstract
The photooxidation reaction of 3,3'-diethyl-9–methylthiacarbocyanine and 3,3'-diethylthiacarbocyanine by viologenes (methyl viologenes, p-chlorophenyl viologenes, p-cyanophenyl viologenes) in acetonitrile and their dimeric complexes with cucurbit[8]uril by monomeric complexes of viologenes in presence of cucurbit[8]uril in water has been studied. The products of photooxidation of dye monomers in acetonitrile are dye dication-radicals and cation-radicals of viologens. The photooxidation of dimeric complexes produces trication radicals of dimeric complexes and cation radicals of monomeric complexes of viologens. The most efficient reaction is the photooxidation of dyes in acetonitrile.
