ABSTRACT
This chapter discusses the electro-optical properties of the compounds only with covalent type of C60 linkage. It reviews properties of fullerenes themselves detected by optical Kerr effect and electro-optical Kerr effect in solutions. The chapter describes electro-optical behavior of C60 adducts, and presents analysis of the behavior of polymeric C60 derivatives in electric field. The solubility of cage carbon particles in organic solvents provides a possibility to study their properties by various methods, including optical and electro-optical Kerr effect, in solutions. For fullerene C60 solvents, heterocyclic solvents N-methylpyrrolidone and N-methylmorpholine are good enough, as these solvent’s ability to dissolve this fullerene is comparable with that of toluene and benzene, traditionally used for extracting C60 from the fullerene soot. Optical and electro-optical Kerr effect methods contributed significantly to the general study of fullerenes and their derivatives. Electro-optical study has shown that the concrete fullerene’s state in the fullerene-containing compound should be considered for the analysis of its electro-optical properties.
