Problems solved by technology

However, since phthalocyanine itself is also a dye intermediate, it can cause secondary pollution during use, and it is easy to aggregate during use, resulting in great limitations in the practical application of photocatalytic degradation. Therefore, the design of phthalocyanine It is necessary to prepare a recyclable photodegradation catalyst that can avoid the agglomeration of phthalocyanine without causing secondary pollution to water resources

Abstract

The invention relates to a porous reticular conjugated polymer containing a phthalocyanine structural unit and a preparation method of the conjugated polymer, belonging to the technical field of functional high molecular materials, and solving the technical problem that the existing phthalocyanine small molecules are unrecyclable and can cause secondary pollution. The porous reticular conjugated polymer is characterized in that the phthalocyanine structural unit is connected to a high molecular main chain frame, and the preparation method is characterized by polycondensation reaction of a carboxyl phthalocyanine derivative and 4,6-diaminoresorcinol hydrochloride. Compared with phthalocyanine small molecules, the content of a pi-electron conjugated system unit is improved, the chemical stability and heat resistance are more excellent, the stability of a photodegradation catalyst is improved, aggregation of phthalocyanine is avoided, the problem that the phthalocyanine small molecules are unrecyclable is solved, secondary pollution is avoided, and the porous reticular conjugated polymer as an environment-friendly green photodegradation catalyst has broad application prospects in industrial dye waste water treatment.

Description

technical field [0001] The invention relates to a porous network conjugated polymer containing phthalocyanine structural units and a preparation method thereof, which is obtained by polycondensation reaction of carboxyl phthalocyanine derivatives and 4,6-diaminoresorcinol hydrochloride , the polymer is used as a photodegradation catalyst and belongs to the technical field of functional polymer materials. Background technique [0002] At present, there are a large number of refractory organic pollutants in industrial production wastewater and human domestic wastewater, which greatly threaten human health. The use of photocatalytic oxidation technology to treat refractory organic pollutants in water, as a new water treatment method, has attracted widespread attention of water treatment experts at home and abroad. Since Professor A.Braun and Professor T.C.Tcherniac first discovered phthalocyanine compounds in 1907, scientists have done a lot of scientific research on photocata...
