Dual-catalytic architectures accommodated by titanium-oxo clusters boosting visible-light-driven C-N cross-coupling <i>via</i> intramolecular electron transfer.

ABSTRACT: Developing dual-catalytic architectures integrating photoactive and transition metal sites holds significant potential for light-driven cross-coupling reactions. This study presents a novel strategy to create synergistic dual-catalytic architectures based on surface engineering of Ti₆-oxo clusters for efficient photocatalytic formation of C-N bonds. Ti₆-oxo clusters are precisely decorated with bipyridine ligands through competitive coordination, followed by the anchoring of iridium photo-sensitizers and nickel catalytic centers to the electron-rich nitrogen sites. The obtained Ni-Ir/Ti₆-Bpca exhibits significantly enhanced charge transfer efficiency via an intramolecular electron transfer mechanism. This integrated design not only boosted catalytic
