Porous metal-organic frameworks (MOFs) are of interest as host materials for molecular sorption and as catalysts various reactions. We are developing porous MOFs that incorporate photosensitizers in the backbone in an effort to develop sorbent materials that generate singlet oxygen to oxidatively decompose adsorbed organic guest molecules. Porous MOFs containing a porphyrin as the photosensitizer were prepared via hydrothermal synthesis by reacting tetra(4-carboxyphenyl)porphyrin with zinc or cobalt nitrate and one of three different bridging ligands in DMF/EtOH at elevated temperature. Photolytic generation of singlet oxygen by the MOF was investigated by monitoring conversion of 1,3-diphenylisobenzofuran to the corresponding diketone using UV-VIS absorption spectroscopy.
