The research focuses on the development of multifunctional metal-organic layers (MOLs) for enhanced photoredox catalysis. The experiments involved the synthesis and characterization of a specific MOL, Hf12-Ir-Ni, which integrates photosensitizing DBB-Ir-F bridging ligands and catalytically active MBA-Ni capping agents. The reactants used in the synthesis include Hf12-Ir-F, MBA capping agents, and NiCl2 for metalation. Various analytical techniques were employed to characterize the MOLs, such as dynamic light scattering (DLS), powder X-ray diffraction (PXRD), high-resolution TEM (HRTEM), 1H NMR spectroscopy, thermogravimetric analysis (TGA), UV-Vis and luminescence spectroscopy, X-ray absorption spectroscopy, and inductively coupled plasma-mass spectrometry (ICP-MS). The photocatalytic performance of Hf12-Ir-Ni was evaluated in three significant single-electron transfer (SET) reactions: C-S cross coupling between aryl iodides and thiols, C-O cross coupling between alcohols and aryl bromides, and C-C cross-coupling between potassium benzyltrifluoroborates and aryl bromides. The MOL demonstrated high efficiency in these reactions, with high turnover numbers and low catalyst loadings, outperforming homogeneous catalysts. The study also investigated electron transfer rates and photocatalytic reaction rates, showing significant enhancements in intra-MOL electron transfer and reactivity compared to homogeneous systems.
