Boris F. Minaev is the head of Chemistry and Nanomaterial Science Department at the Bohdan Khmelnytsky National University in Cherkasy, Ukraine.He was awarded the Honored Worker of Science and Technology of Ukraine on 2012. He was awarded Life achievements award from American Biographic Institute for “The Singlet Oxygen Emission Theory”on 1999. He is the leader and coordinator of national research projects: a number of projects (five) in organic synthesis and electronic structure calculations for development of OLED technology (2008-2021) governed by Ministry of Education and Science in Ukraine.

摘要：

Specific physico-chemical properties of the diatomic oxygen molecule are due to incompleteness of the outer pi_g-electronic shell. Oxygen is a paramagnetic gas and can both quench and sensitize luminescence of organic compounds; it acts as a catalyst of some chemical transformations and as an oxidant in many biochemical processes, in particular, respiration and combustion. Chemical reactions of oxygen with organic substances are forbidden by spin selection rule. Solvent effect on radiative lifetime of singlet oxygen is very instructive from the point of discovering of biochemical activation of O2 reactions.
