Essay

The thesis is devoted to the synthesis and study of the physical (electrical, mechanical, and thermodynamic) properties of functional nano- and composite materials based on Fe(II) spin-crossover (SCO) complexes containing pyrazine. In the first chapter, a literature review is provided, which briefly describes the phenomenon of spin crossover and its characteristics in a specific class of complexes ‒the Hofmann-type clathrate analogues. It also outlines the types of functional nano- and composite materials with SCO, methods of their synthesis and characterization of properties. The main application areas of functional materials with SCO and the key scientific achievements in these areas are discussed.
