虽然已知通过冷却无机非金属、有机和金属物种的熔融状态而形成的玻璃，但那些同时包含无机和有机部分的玻璃要少得多。然而，由有机配体连接的无机节点组成的网络材料确实存在于晶态或非晶态领域。在过去的二十年里，这种被称为金属有机骨架(MOF)或配位聚合物的开放框架化合物的大家族被广泛研究，几乎所有的应用都源于它们高的内表面积和化学上的多功能性。最近，一些MOF被证明在冷却时会熔化和玻璃化。在这里，总结了这些最新的发现以及MOF化学和玻璃科学领域之间的联系。重点介绍了利用结晶态的可调化学制备MOF玻璃的可能优势和应用。
While glasses formed by quenching the molten states of inorganic non-metallic, organic, and metallic species are known, those containing both inorganic and organic moieties are far less prevalent. Network materials consisting of inorganic nodes linked by organic ligands do however exist in the crystalline or amorphous domain. This large family of open framework compounds, called metal-organic frameworks (MOFs) or coordination polymers, has been investigated intensively in the past two decades for a variety of applications, almost all of which stem from their high internal surface areas and chemical versatility. Recently, a selection of MOFs has been demonstrated to undergo melting and vitrification upon cooling. Here, these recent discoveries and the connections between the fields of MOF chemistry and glass science are summarized. Possible advantages and applications for MOF glasses produced by utilizing the tunable chemistry of the crystalline state are also highlighted.
