Synthesis And Photocatalytic Properties Of Porous Metal Phthalocyanine Polymers

Metallophthalocyanines,which are macrocyclic molecules with a planar conjugated array of 18-? electrons,are identified as the most promising visible-light photocatalyst due to their outstanding absorption in the visible light region.However,metallophthalocyanines are easy to form dipolymers in aqueous solution,which significantly reduces their catalytic activity,and limits their development in the visible-light photocatalysis field.With the rapid development of porous organic materials,more and more multifunctional materials have been synthesized and successfully used in related fields.Based on the multifunctional properties of metallophthalocyanines structure,we have prepared a series of porous organic materials based on the metallophthalocyanines framework,which integrate the advantages of both metallophthalocyanines and porous organic materials.Herein,firstly,the series of MPc?NO₂?₄?M=Co,Cu?were synthesized by solid phase method,and then they were converted to the MPc?NH₂?₄?M=Co,Cu?.Subsequently,the metallophthalocyanine-based conjugated microporous polymers MPc-CMPs?M=Co,Cu?were synthesized by polycondensation reaction with MPc?NH₂?₄?M=Co,Cu?and 1,4-phthalaldehyde.The structure of MPc-CMPs?M=Co,Cu?was elucidated by FTIR,UV-vis and XRD,et al.The visible-light photocatalytic properties of MPc-CMPs?M=Co,Cu?were investigated by using organic dye rhodamine B as target degradation,hydrogen peroxide as oxidant,and MPc-CMPs?M=Co,Cu?as visible-light photocatalyst.In addition,we also demonstrated their recycling performance.The experimental results show that the series of MPc-CMPs?M=Co,Cu?have good visible-light photocatalytic performance.
