Synthesis and Study of Differentially Substituted Dibenzotetraazafulvalenes
摘要:
A series of functionalized dibenzotetraazafulvalenes have been synthesized and characterized using X-ray crystallography, UV-vis spectroscopy, and cyclic voltammetry. The solid-state structures, electronic properties, and redox potentials of these compounds varied in accordance with the nature of the pendant arene substituent.

The purpose of the present invention is to provide a nonaqueous electrolyte that contains acetonitrile having an excellent balance between viscosity and the dielectric constant and a fluorine-containing inorganic lithium salt, wherein the generation of complex cations comprising a transition metal and acetonitrile is suppressed, excellent load characteristics are exhibited, and increases in internal resistance upon repeated charge/discharge cycles are suppressed; a further purpose of the present invention is to provide a nonaqueous secondary battery. The present invention relates to a nonaqueous electrolyte which contains: a nonaqueous solvent comprising acetonitrile; a fluorine-containing inorganic lithium salt; and a specific nitrogenous cyclic compound typified by benzotriazole.
