Water stability in metal-organic frameworks (MOFs) is critical for several practical applications. While water instability is mainly thought to stem from linker hydrolysis, MOFs with strong, hydrolysis-resistant metal-linker bonds can be susceptible to damage by capillary forces, which cause cavities and channels to collapse during activation from water. This study utilizes metal node functionalization as a strategy to create vapor-stable and recyclable MOFs.
金属有机框架材料（MOFs）中的水稳定性对于多个实际应用至关重要。虽然通常认为水不稳定性主要源于连接体水解，但具有强的、抗水解金属-连接体键的MOFs可能易受毛细管力的破坏，毛细管力会导致在从水中活化过程中空腔和通道坍塌。本研究采用金属节点功能化作为一种策略来制备气相稳定且可循环使用的MOFs。
