Metal–organic frameworks (MOFs) are well known for their versatile applications in diverse fields (e.g., gas adsorption, water purification, sensing, drug delivery, and catalysis). The basic properties of most MOFs (e.g., morphology and structure) are, however, known to be affected sensitively if exposed to moisture/water. Consequently, it is necessary to conduct a comprehensive assessment on the stability of MOFs in relation to variables associated with such property changes (e.g., reduction in the surface area and structural collapse). In this article, factors and processes affecting the aqueous stability of diverse MOFs (e.g., imidazolate and carboxylate frameworks) are discussed. This article will thus help researchers properly assess the influence of water on the stability of MOFs so that suitable strategies can be established for the development of water-stable MOFs and for their efficient applications toward diverse fields (e.g., separation/storage of gases and adsorption/photocatalysis/sensing of pollutants in aqueous systems).

水稳定性在金属-有机框架中的关键作用以及扩展其适用性的先进修饰策略

金属有机框架（MOF）在多种领域（例如，气体吸附，水净化，传感，药物输送和催化）的广泛应用而闻名。但是，已知大多数MOF的基本特性（例如，形态和结构）如果暴露于湿气/水中都会受到敏感影响。因此，有必要对MOF的稳定性进行全面评估，以评估与此类特性变化相关的变量（例如，表面积减少和结构塌陷）。在本文中，影响多种MOF的水稳定性的因素和过程（例如，咪唑酯和羧酸酯骨架）。因此，本文将帮助研究人员正确评估水对MOF稳定性的影响，以便为开发水稳定性MOF以及将其有效应用于多种领域（例如，气体的分离/存储和吸附）建立合适的策略。/光催化/感应水性系统中的污染物）。
