Radical anion and coordination compounds of polyconjugated molecules:potential organic materials with unusual magnetic, conducting and optical properties

Radical anion salts and coordination complexes of fullerenes, macrocycles and organic dyes obtained by reduction are considered. The reduction transfers an electron to these molecules enabling their participation in magnetic coupling of spins and/or high conductivity as well as modifies essentially their optical properties. Different types of electron transfer between the components have also been observed for these compounds. This review presents new approaches to the syntheses of these salts and complexes as well as their structural and physiochemical properties. Prospects for the development of this area are discussed.
