Beyond coordination and covalent bonds: Stabilization strategies and emerging applications of metal hydrogen-bonded organic frameworks

Metal‑hydrogen-bonded organic frameworks (MHOFs) represent an emerging class of crystalline porous materials constructed through the hydrogen-bond-directed self-assembly of metal-organic units. While offering versatile functionality, MHOFs present a greater synthetic challenge compared to established frameworks such as metal-organic framewoks (MOFs) and covalent organic frameworks (COFs), primarily due to the relatively weak nature of hydrogen bonds versus coordination or covalent linkages. Nevertheless, through rational design of metal-organic building blocks, careful control of acidity/basicity, and strategic topological planning, stable and permanently porous MHOFs can be successfully realized.
