Abstract
Two nanoporous perylene bis-imide linked metalloporphyrin framework catalysts have been synthesized via condensation of 5,10,15,20-tetrakis-(4\(^{\prime }\)-aminophenyl) iron(III) porphyrin chloride or 5,10, 15,20-tetrakis-(4\(^{\prime }\)-aminophenyl) manganese(III) porphyrin chloride with perylene-3,4,9,10-tetracarboxylic dianhydride. Both the materials were crystalline in nature and were characterized by electron microscopy techniques, solid-state 1H- 13C CP/MS NMR, powder X-ray diffraction (PXRD), and magnetic susceptibility measurements. The nitrogen gas physisorption study has indicated that both materials are porous in nature and have BET surface area with 653 m2/g and 974 m2/g with uniform pore size of 2.8 nm. These materials were found to act as very good heterogeneous catalysts for selective oxidation of alkanes and alkenes with tert-butyl hydroperoxide and were not degraded even after multiple uses up to 10 cycles. Two nanoporous perylene bis-imide linked metalloporphyrin framework catalysts have been synthesized. They show interesting peroxidase activity for the selective oxidation of alkanes and alkenes even after ten cycles with negligible catalyst degradation.
