- Abstract
The effect of cucurbit[7]uril on the phototransformation of 3,3′-diethylthiacarbocyanine iodide dye in aqueous solution has been investigated by nanosecond laser flash photolysis. The presence of cucurbit[7]uril results in the formation of its complex with the dye molecule producing a dimer. The dimer formation is evident from the ground and triplet-triplet absorption spectra. The dimers in the triplet state are capable of electron transfer. The structure of the complexes is suggested on the basis of quantum chemical calculations.
