摘要
A metalloporphyrin-based porous organic polymer, Mn-PPOP-1, was constructed in high yield via the ketoenamine condensation of robust porphyrin tetraamines (TBPP) with 1,3,5-triformylphloroglucinol. The stable keto-enamine form in the synthesized polymer was unambiguously confirmed by C-13 CP-MAS solid state NMR. Noticeably, besides the high thermal and chemical stability, this material contains both micropores and mesopores, which are favorable for mass transfer in the catalytic application. Mn-PPOP-1 exhibits significantly high catalytic oxidation of olefins and arylalkanes at room temperature. The catalytic activity and stability of Mn-PPOP-1 are apparently superior to those of the homogeneous manganese porphyrins. These results indicate that the metalloporphyrin-based porous organic polymer is a promising candidate for efficient heterogeneous catalysts.
