Enhanced Catalytic Activity through the Tuning of Micropore Environment and Supercritical CO_2 Processing: Al(Porphyrin)-Based Porous Organic Polymers for the Degradation of a Nerve Agent Simulant

摘要

An Al(porphyrin) functionalized with a large axial ligand was incorporated into a porous organic polymer (POP) using a cobalt-catalyzed acetylene trimerization strategy. Removal of the axial ligand afforded a microporous POP that is catalytically active in the methanolysis of a nerve agent simulant. Supercritical CO_2 processing of the POP dramatically increased the pore size and volume, allowing for significantly higher catalytic activities.
