Coordination and photochemical properties of magnesium complexes of chlorins and their aggregates towards hydrogen peroxide were considered. Тhe binding energy of H 2O and H 2O 2 with chlorophyll and chlorophyllide depending on their form (monomers, dimers and trimers) was estimated by quantum chemical calculations. It is shown that at an increase of the degree of the pigment aggregation binding energy of H 2O 2 was more than the energy of H 2O. Analysis of experimental results of the photochemical decomposition of hydrogen peroxide using chlorophyll was carried out.
