These results show that interconversion of reactive oxygen species in photocataly-
sis of metal complexes of porphyrins in the certain cases is able to provide energy stor-
age reaction with increase of the chemical potential. On the one hand, it is important
for the development of processes of utilization of solar energy. On the other hand, it
is of interest to study the energy of intracellular biochemical processes involving the
pharmacologically active metal complexes.

9.4 CONCLUSION
The model photosensitive systems with hydrogen peroxide participation were pre-
pared. Immobilized metal complexes of porphyrins and Chl shown to possess a cata-
lytic activity in the reaction of ɇ 2 Ɉ 2 decomposition. Linear correlations between the
photovoltaic and photocatalytic properties of non-transition metal complexes of TPP
were found. It was demonstrated that electron transfer from ɇ 2 Ɉ 2 to acceptor mol-
ecules under visible light irradiation is possible.
