520 3 |a It was found that bis(2-benzimidazolyl)bisthiazole deposited on nanosized TiO2 in the presence of Zn2+ salts was able to generate a photocurrent upon irradiation by visible light in a cell with a solution of KI in acetonitrile. The activity of this compound was probably caused by the presence of the benzimidazole fragment (electron donor) and the bisthiazole group (electron acceptor), while zinc(II) played a role of agent, required for formation of an insoluble coordination compound on the surface of the TiO2. From comparison of the results with published data it can be concluded that the open-circuit potential of photovoltaic cells containing a benzimidazole fragment decreases with decrease in the energy of lowest unoccupied molecular orbital.
