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：

Theoretical views on the mechanisms of overcoming spin prohibitions in photo-processes and in enzymatic activa-tion of the O2 molecule are considered. The electronic struc-tures of various quantum states of this molecule and collision complexes of oxygen with other molecules are given. The patterns of biochemical activation of O2 through T7S tran-sitions in enzymatic complexes are proposed. It is noted that the enhancement mechanisms for specific exchange interac-tions in enzymatic complexes have common features with mechanisms of physical photoactivation of oxygen.
