It was established that the supramolecular system is based on metalocrown ions Ho3 + and Cu2 +, combined by tris-oksalatochromate, exhibits properties of molecular magnets. Found that ligands containing benzimidazole, thiophene groups or substituted tiazolotiazole and coordinated to Zn2 + ion in most cases is showed bathochromic shift, charge transfer band also can appeared, which should contribute to the activity of photovoltaic systems. For the first time it is found that benzimidazole fragment is able to act as electron donor in photovoltaic cells. Among the studied systems zinc complex with ligand containing triphenylamine fragment reveaked the best photovoltaic activity. Based on the study of a number of complexes Gd3 +, Eu3 + and Tb3 + with tris-pirazolylborate ligands that revealed the structure of supramolecular coordination polymers it is shown that in such systems the excitation energy is able to be transferred from the site of absorption of a photon to the emitting center over long distances by p-stacking interactions along 1D chain.
