Embodiment 1

[0030] Synthesis of Dinuclear Subphthalocyanine

[0031] Under nitrogen protection, 0.386 g of ground 4-nitrophthalonitrile and 0.186 g of bisphenol were dissolved in 15 mL of DMF, heated to 70°C for 3.5 hours, and catalyst K was added. 2 CO 3 0.552g, continue to react at 70°C for 3.5h, and finally cool to room temperature, then pour the reaction mixture into an ice-water mixture to produce a flocculent precipitate, let stand, and filter with suction to obtain a crude product, which is finally obtained by recrystallization The final product is a tetranitrile precursor.

[0032] Under nitrogen protection, 0.438 g of the prepared tetranitrile precursor and 0.521 g of phthalonitrile were dissolved in 20 mL of dry dichlorobenzene, 0.29 mL of BBr3 was added, and the reaction system was stirred at -10 °C for 0.5 h, and then The temperature was gradually raised to 180°C in 0.5h and held for 6h. After the completion of the reaction, after cooling to room temperature, the solvent wa...

Abstract

The invention discloses a preparation method of a dinuclear subphthalocyanine substance. The preparation method is as follows: take 4-nitrophthalonitrile as the starting raw material, make it react with bisphenols in the solvent DMF to undergo a nucleophilic substitution reaction to prepare a tetranitrile precursor, and then use the synthesized tetranitrile and phthalonitrile as the initial substance of the reaction, in a high-boiling aromatic solvent, undergo a cyclopolymerization reaction with boron tribromide or boron trichloride to obtain a binuclear subphthalocyanine compound, and finally the prepared binuclear subphthalocyanine And the phenolic substance is dissolved in the aromatic solvent, under the catalysis of pyridine, the dinuclear subphthalocyanine substance is prepared, and the preparation method is simple and easy. The invention also provides the application of the binuclear subphthalocyanines as a catalyst in Li / SOCl2 batteries.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a preparation method of a dinuclear subphthalocyanine and its use as a catalyst in Li / SOCl 2 battery applications. Background technique [0002] Subphthalocyanine is an organic macrocyclic compound with a 14-π electron conjugated system composed of three isoindoline units. It was first synthesized by A. Meller et al. in 1972, and two years later by Kietaibl using X-ray diffraction. The method determined its molecular structure, which can be regarded as the isomer of phthalocyanine in a broad sense. Due to the larger electron conjugated system, subphthalocyanines have good thermal stability, photostability, nonlinear optics and other properties. The synthesis of dinuclear subphthalocyanine was first reported by Kobayashi, using phthalonitrile and phthalonitrile as raw materials. Compared with mononuclear subphthalocyanine, it has a larger electron conjugated system, so it has...
