Chemical and mechanical modifications of flexible metal-organic frameworks for enhancing photocatalysis.

ABSTRACT: Postsynthetic modification (PSM) has been widely employed to enhance the functionality of metal-organic frameworks (MOFs) for applications such as gas storage, light harvesting, and catalysis. However, the critical role of framework flexibility in enabling diverse modification pathways and influencing framework properties remains underexplored. In this work, we demonstrate that flexible MOFs offer unique advantages for PSM, using the flexible PCN-128 as a platform for both chemical and mechanical modifications to enhance photocatalytic CO₂ reduction activity. Mechanical force induces piezochromic behavior, while sequential postsynthetic annulation reactions extend the π-conjugation of aromatic ligands within PCN-128, both modulating the energy band positions and enhancing visibl
