RESUMEN
The exploration of novel structures and structural transformation of supramolecular assemblies is of vital importance for their functions and applications. Herein, based on coordination-driven self-assembly, we prepare a neutral truncated tetrahedron and a heteroleptic truncated octahedron, whose structures are unambiguously confirmed by X-ray diffraction analysis. More importantly, the truncated tetrahedron is quantitatively transformed into the truncated octahedron through its fusion with another cationic truncated tetrahedron, as evidenced by fluorescence, mass and NMR spectroscopy. This study not only deepens our understanding of the process of supramolecular fusion but also opens up possibilities for the subsequent preparation of advanced supramolecular assemblies with complex structures and integrated functions.
RESUMEN
Metal-organic frameworks (MOFs) and metal-organic cages (MOCs) have garnered significant attention as promising photocatalysts due to their tunable chemical structures and integrated multifunctionality. To increase the photocatalytic efficiency, strategies like ligand functionalization, introducing additional catalytic sites, and doping or encapsulating photosensitizers have been explored for both MOFs and MOCs. This concept review focuses on recent advancements in utilizing MOFs and MOCs for photocatalytic hydrogen production, highlighting their unique characteristics and introducing their respective mechanisms in this field. Moreover, it outlines the current challenges and prospects faced by MOFs and MOCs, offering an outlook on their future in this domain.
