Abstract
The binding of nanoparticles zeolite with a number of cationic porphyrins are studied. Previously, it was established that the main mechanism of binding the zeolite nanoparticles with cationic porphyrins is an ionic bond. Since binding of porphyrins as ligands to nanoparticles at the initial stage of interaction is determined by the Brownian motion of porphyrins, it is obvious that the interaction of porphyrins with nanoparticles may depend on the temperature. In the present paper by methods of absorption and fluorescence spectroscopy was studied the complexation of porphyrins with zeolite nanoparticles at different temperature conditions. It was established that there is a clear temperature dependence of the complexation of cationic metalloporphyrins with zeolite naonoparticles, and for correct determination of the percentage of binding must be strict thermostating of the experimental conditions.
