The ligands in metal-organic framework (MOF) play as light absorption center and transfer photogenerated electrons to metal node through ligand-to-metal charge (LMCT) during photocatalysis, energy utilization efficiency is strongly restricted by the inertness of ligands. Herein, a ligand updating strategy proposed inserting centers MOFs activate inherent ligands, realizing boosting hot electron generation photocatalytic activities via cascaded proceeding transfer. By taking PCN-777 (a zeotype mesoporous Zr-containing MOF) an example, this study shows that embedded 1-pyrenecarboxylic acid (PCA) can triplet-triplet transfer, where triplet excitons would dissociate into photocarriers migrating Zr cluster LMCT process. As expected, PCN-777-PCA exhibits promising activity metallaphotocatalytic C─N cross-coupling reactions offering abundant for involved dual photoredox cycles. This work provides practical method improving application updating.
