摘要：
Photosensitive heterostructures containing titanium dioxide and a sensitizer, viz., a cyanine dye with two conjugated chromophores have been obtained. Their absorption spectra have been studied, and their photocatalytic activity has been demonstrated to depend on the dye content and irradiation conditions. The energetics of possible electronic processes induced by light of various spectral ranges is considered. Some explanationsare proposed for the observed regularities.
