Kinetic Measurements of Singlet Oxygen Phosphorescence in Hydrogen-Free Solvents by Time-Resolved Photon Counting
Solvents lacking hydrogen atoms are very convenient models for elucidating the properties of singlet oxygen, since the lifetime of singlet oxygen in these solvents reaches tens milliseconds. Measuring intrinsi...

Primary mechanisms of photoactivation of molecular oxygen. History of development and the modern status of research
This review starts from a brief historical account devoted to the principles of the Bach-Engler peroxidation theory and experiments and ideas which led A. N. Bach to its creation. Then, the discovery of photod...

Pathways of chemical evolution of photosynthesis
The primary metabolism of protobionts was probably based on the electron transfer reactions regulated by catalysts or photosensitizing pigments. The action of photoreceptive pigments was inevitable in the case...

Abiogenic Formation of Porphin, Chlorin and Bacteriochlorin
Oparin’s hypothesis (1) maintaining that a prolonged chemical evolution preceded the emergence of life on Earth gave impetus to numerous investigations whose purpose was to reveal probable pathways of biosynth...
