Donor-Acceptor Interactions Research Group

The work of the scientific group is associated with the synthesis and characterization of donor-acceptor (DA) complexes in all aggregate states: in the solid, gas and liquid phase. In particular, the structural features of DA complexes, their thermal stability and the processes under heating, donor-acceptor stabilization of small molecules and inorganic heterocycles, gas-phase reactions involving DA complexes, and chemical deposition from the gas phase are studied.
