Integration of individual molecular components in a structurally controlled manner remains one of the challenges of artificial photosynthesis. Metal organic frameworks (MOFs) can serve as such a platform to integrate different functionalities. We have incorporated catalytically competent Ir, Re, and Ru complexes as dicarboxylate ligands into highly stable and porous UiO frameworks. The resultant MOFs were active catalysts in a range of reactions that are relevant to solar energy utilization, such as water oxidation, photocatalytic proton and CO2 reduction and organic transformations. Taking advantage of site-isolation of the immobilized catalysts and the heterogeneous nature of MOF, we were able to perform studies that are not possible in homogeneous systems. With hierarchical design, we achieved synergistic operation of different components in the same framework, leading to enhanced light harvesting efficiency and photocatalytic activity. The presented work illustrates the potential of combining molecular catalysts and MOF structures in developing systems for solar energy utilization.
