Paragraph 0047-0048, (2020/09/12)
The invention discloses a synthesis method of tetraaryl nickel porphyrin catalyzed by anhydrous aluminum trichloride, which comprises the following step: refluxing aromatic aldehyde, pyrrole and nickel salt in a DMF solvent under the catalysis of anhydrous aluminum trichloride to synthesize tetraaryl nickel porphyrin in one step. The reaction process comprises the following steps: sequentially adding anhydrous aluminum trichloride, aryl aldehyde, pyrrole and nickel salt into DMF (Dimethyl Formamide) while stirring, stopping the reaction after heating reflux reaction for a certain time, cooling, standing overnight near 273K, and carrying out suction filtration to obtain a nickel porphyrin crystal. According to the method, aromatic aldehyde, pyrrole and nickel salt are directly used as raw materials, porphin is not needed, strongly corrosive organic acid is not used as a solvent, high-purity tetraaryl nickel porphyrin is obtained at a high yield under the condition that a complex separation means is not needed, and industrial production is easy to achieve.

(Figure Presented) Bowled over: Calix[3]dipyrrins were synthesized from pyrrole and aryl aldehyde precursors by the Lindsey protocol, modified by the presence of a small amount of water. These bowl-shaped macrocycles can accommodate three metal (M) ions such as NiII and CuII in a hexagonal M3O3 manner (see structure; Cu green, N blue, O red, C black).
