Enhanced Catalytic Activity through the Tuning of Micropore Environment and Supercritical CO₂ Processing: Al(Porphyrin)-Based Porous Organic Polymers for the Degradation of a Nerve Agent Simulant

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 CO₂ processing of the POP dramatically increased the pore size and volume, allowing for significantly higher catalytic activities
