The work is devoted to solving an important problem of developing the fundamental concepts of the interconnection between the chemical structure of molecular systems based on cobalt(II) complxes with macrocyclic tetrapyrrole ligands and fullero[60/70]pyrrolidines or gold(III) porphyrinates and their physicochemical properties, including optical properties in the ground and excited states, photoelectrochemical parameters of photoinduced processes and self-assembly reactions.
The researcher has developed new concepts in the field of physical and inorganic chemistry of cobalt(II) coordination compounds with porphyrin and phthalocyanine ligands and their supramolecular axial complexes with fullero[60/70]pyrrolidines or gold(III) porphyrinates to reveal the interconnection between the chemical structure and composition of the axial complexes, their stability, formation rate, spectral characteristics in the ground and excited states.
The work proposes an approach to obtaining new systems with a photo-induced electron transfer based on using complexes of cobalt(II) with macrocyclic tetrapyrrole ligands as electron donors and fullero[60/70]pyrrolidines or gold(III) porphyrinates as electron acceptors.
The author proposes a methodology for establishing the effect of chemical structure on the dynamics of ultrafast photo-induced processes in molecular systems with a photo-induced electron transfer based on cobalt(II) with macrocyclic tetrapyrrole ligands as electron donors and fullero[60/70]pyrrolidines or gold(III) porphyrinates by combining methods of stationary and time-resolved absorption fluorescent spectroscopy and quantum chemical calculations.
The researcher has shown the prospects of using supramolecular systems based on porphyrin and phthalocyanine cobalt(II) complexes and fullero[60/70]pyrrolidines or gold(III) porphyrinates in the development of photovoltaic cells.
