Generation of reactive oxygen species under singlet oxygen photosensitivity by chlorophyll and its analogs
Autor: K. S. Davydov, G. I. Kobzev, A. V. Lobanov, G. G. Komissarov
Publikováno v: Russian Journal of Physical Chemistry B. 8:277-283
The kinetic and photochemical parameters of the generation of reactive oxygen species, including singlet oxygen photosensitized by chlorophyll and its analogs on the basis of magnesium complexes of tetrapyrroles, are determined. It is shown that the

Hydrogen peroxide in artificial photosynthesizing systems
Autor: G. G. Komissarov, A. V. Lobanov
Publikováno v: Biophysics. 59:169-182
From the point of view of the concepts of hydrogen peroxide as a source of photosynthetic oxygen (hydrogen) coordination and photochemical properties of chlorophyll and its aggregates towards hydrogen peroxide were considered. The binding energy of H

Highly reactive intermediates in photochemistry of chlorophyll
Autor: A. V. Lobanov, G. G. Komissarov
Publikováno v: Biophysics. 58:51-55
It is shown that chlorophyll (Chl) has photochemical activity in the reduction of O2 to H2O2. In the case of the monomeric forms of Chl, H2O2 formation occurs with the participation of 1O2, ⊙OH and O2⊙−. Activity of Chl depends on its microenvi

Effect of the molecular structure of films of tetrapyrrole compounds on their photoelectrochemical characteristics for different types of sensitization
Autor: G. G. Komissarov, V. A. Ilatovskii, G. A. Ptitsyn
Publikováno v: Russian Journal of Physical Chemistry B. 2:936-939
It was examined how the photoelectrochemical properties of thin films (50 nm) prepared from metal derivatives of tetrapyrrole compounds with various central atoms depend on the character of sensitization. It was demonstrated that the treatment of pig
