Selective Photocatalytic Conversion of Benzyl Alcohol to Benzaldehyde by Antimony(V) Porphyrin Metal‐Organic Frameworks under Visible‐Light Irradiation

Abstract Porphyrin‐based MOFs have great structural tunability and prominent catalyst activity. In this work, a series of antimony porphyrin MOFs ( PCN‐224(Sb)‐L ) were synthesized to efficiently selective oxidate benzyl alcohol under visible light. To investigate the effects of the Sb‐axial ligands on photocatalytic activity, the oxidation of benzyl alcohol to corresponding benzaldehyde was utilized as a model reaction. Within these three analogues of PCN‐224(Sb)‐L , PCN‐224(Sb)‐OH exhibit a remarkable 96 % conversation and 100 % selectivity of the benzaldehyde with an extremely high turnover number (TON) of 9300.
