Embodiment 1

[0037] Example 1. Dissolve a certain amount of phthalimine (4,4'-dihydroxy) salicylaldehyde Schiff base cobalt complex Co (di-OHSalphen) in 3.1% NaOH aqueous solution, and add the raw material complex 10% cetyltrimethylammonium bromide by mass, add the dichloroethane solution dissolved with copper phthalocyaninesulfonyl chloride 1 to 2 times the mass of the raw material complex under vigorous stirring, continue to stir and react for 2 hours, and pump Filter, wash with 2% NaOH aqueous solution, ethanol and water respectively 3 times, vacuum-dry, obtain black flaky high polymer---polymer Schiff base cobalt-copper phthalocyanine double metal complex, productive rate is 60% .

Embodiment 2

[0038] Example 2, a certain amount of phthalimine (4,4'-dihydroxy) salicylaldehyde Schiff base cobalt complex Co (di-OHSalphen) was dissolved in 3.1% NaOH aqueous solution, and the amount of the raw material complex was added 8% cetyltrimethylammonium bromide, under vigorous stirring, add the dichloroethane solution dissolved with nickel phthalocyaninesulfonyl chloride 1 times the mass of the raw material complex, continue to stir and react for 2h, then suction filter, and use 2% NaOH aqueous solution, ethanol and water were washed three times respectively, and vacuum-dried to obtain a sheet-like polymer—a polymer Schiff base cobalt-nickel phthalocyanine bimetallic complex with a yield of 60%.

Embodiment 3

[0039] Example 3, a certain amount of phthalimine (4,4'-dihydroxy) salicylaldehyde Schiff base cobalt complex Co (di-OHSalphen) was dissolved in 3.1% NaOH aqueous solution, and the raw materials were added to compound Cetyltrimethylammonium bromide with a substance mass of 1-10%, add the dichloroethane solution dissolved with manganese phthalocyaninesulfonyl chloride 1-2 times the mass of the raw material complex under vigorous stirring, and continue stirring for 2 hours After that, it was suction filtered, washed three times with 2% NaOH aqueous solution, ethanol and water respectively, and dried in vacuum to obtain a high molecular weight Schiff base cobalt-manganese phthalocyanine double metal complex with a yield of 61%.

Abstract

This invention discloses a giant molecule Schiff's base-phthalocyanine thermometal coordination compound and its preparation. The preparation of this giant molecule Schiff's base-phthalocyanine thermometal coordination compound is made by interface fasculation of orth-benzene di-imido mini-(4,4'-di-hydroxy group )salicylaldehyde Schiff's base transition metal coordination compound and phthalocyanine sulfochlorides transition metal coordination compound. This giant molecule Schiff's base-phthalocyanine thermometal coordination compound contains double active center, possessing very strong Catalytic Properties.it can be used to catalyze molecule oxidizing reaction, especially to produce catalyst of allotri-propylbenzene hydrogen dioxide.

Description

technical field [0001] The invention belongs to the field of polymer technology, and relates to a polymer catalyst, in particular to a polymer catalyst prepared by using a Schiff base metal complex and a metal phthalocyanine complex—a polymer Schiff base-phthalocyanine bimetallic complex things. Background technique [0002] Due to the unique structure and properties of porphyrin, it has been widely used in chemistry, biochemistry, medicine, material science and other fields. Studies have shown that metal porphyrin complexes can catalyze the activation of molecular oxygen under mild conditions, especially small molecular compounds and high molecular porphyrin metal complexes have received extensive attention in the field of biomimetic catalytic oxidation. However, people have also found many unfavorable factors in the preparation and use of porphyrins during the experiment, among which the low synthesis yield and high price are particularly prominent. Among the porphyrin-l...
