Abstract

The invention discloses a multihole metal porphyrin organic covalent polymeric material and a preparation method and application of the material. The polymeric material takes tetra-amino phenyl porphyrin as a basic raw material and is polymerized by reaction with cyanuric chloride under a mild condition to form a multihole organic covalent polymeric material CPF-1; the CPF-1 is a basic carrier and is further synthesized into the metal porphyrin organic covalent polymeric material Mn-CPF-1 with a large porphyrin ring loaded with metal ions Mn III through the reaction with manganese metal salt. The multihole metal porphyrin organic covalent polymeric material is applied to catalytic epoxidation olefin and catalytic oxidization aromatic hydrocarbon; the reaction condition is mild; pollution is avoided; the stability is high; the cost is low; a catalyst can be simply recycled and reused; the multihole metal porphyrin organic covalent polymeric material is high in conversion rate; a product is high in selectivity; the post-treatment is simple.
