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.

hexanuclear organometallic cages of composition [Ag6(3 a,b)4](PF6)6 from the reaction of benzimidazole‐derived tris(azolium) salts [H3‐3 a,b](PF6)3 with Ag2O was achieved. The molecular structures of the cages were established by X‐ray diffraction studies along with NMR and MS analyses. The existence of a single assembly in solution was supported by diffusion‐ordered spectroscopy (DOSY) 1H NMR spectra
