Postsynthetic Modification of Hydrogen‐Bonded Frameworks

Abstract Hydrogen‐bonded frameworks have garnered significant attention due to their flexible structures with tailored porosity, making them a promising class of porous framework materials. However, the direct synthesis of hydrogen‐bonded frameworks with specific functions is highly challenging due to the unpredictable formation of hydrogen‐bonded frameworks. In response, postsynthetic modification has emerged as a potent strategy to imbue desired functions into hydrogen‐bonded frameworks. Recent advances have demonstrated the effectiveness of postsynthetic modification in hydrogen‐bonded frameworks for studying their mechanical, luminescent, electrochemical, and chiral properties. In this concept, we comprehensively summarize the methodologies and outcomes of postsynthetic modification to hydrogen‐bonded frameworks, providing a highlight of this exciting research area.
