N2 - In this study the syntesis and characterization of meso-substituted Sn and Co porphyrinnanostructures were carried out. The effect oh pH of medium on the formation of Sn/Co- porphyrin nanostructures was studied. The formation process is caused by the net charge on the porphyrin, which is controlled by protonation/derotonation of the oppositely charged periphery. This charge determines also stoichiometric ratios of porphyrins in the nanostructures. It was found that the contact of the donor (Co-porphyrin) with acceptor (Sn-porphyrin) provides photoconductivity of nanostructures under illumination with visible light. It was shown that the increase of temperature deacreases their conductance both in the dark and under illumination.
