Abstract

The invention relates to a method for directly synthesizing nickel phthalocyanine crystal by using a solvent thermal method, solving the problems of long growth period, small size of the obtained crystal, low success rate, high cost and the like existing in the prior nickel phthalocyanine crystal preparation method. The method for directly synthesizing nickel phthalocyanine crystal by using the solvent thermal method comprises the following steps: using quinoline as the solvent and dihydrate nickel acetate and indole as the starting materials, adding the dihydrate nickel acetate and the indoleinto a reaction kettle according to the mol ratio of 1:2-5, then adding quinoline solvent, reacting for 7-10 hours at the temperature of 200-300 DEG C, and cooling to the room temperature; and finally filtering to directly obtain the purple acicular nickel phthalocyanine crystal. With the method, the single crystal growth time is greatly shortened, and single crystal can grow to 10mm within ninehours; in addition, the solvent is easily removed; and the method has the success rate of 100 percent, simple structure, short reaction time, low cost and high yield which can reach more than 70 percent.

Description

technical field [0001] The invention relates to a nickel phthalocyanine synthesis technology, in particular to a method for directly synthesizing nickel phthalocyanine crystals by a solvothermal method. Background technique [0002] Phthalocyanine is a macrocyclic compound, and there is a hole in the ring, which can accommodate metal elements such as iron, copper, cobalt, aluminum, nickel, calcium, sodium, magnesium, zinc, etc., and combine to form metal complexes. The metal atom replaces the two hydrogen atoms located in the center of the planar molecule. Due to the formation of a coordination compound with the metal element, there are only 16 π electrons in the metal phthalocyanine molecule. Covalent bonds and coordinate bonds are essentially equivalent, and more than 5,000 phthalocyanine compounds have been prepared so far. Phthalocyanine is not just a colorant, but more importantly, it is a multifunctional material. The application of derivatives has been involved in s...
