The field of metal–organic frameworks (MOFs) has been incorrectly believed to be purely crystalline. However, non-crystalline MOFs (amorphous MOFs, MOF liquids, and MOF glasses) are starting to emerge as alternative materials, beyond the dictatorial domain of crystalline MOFs. Non-crystalline MOFs present many opportunities, either as novel functional materials themselves, or as vehicles to create other materials. In this extensive Review, we describe the two approaches to preparing amorphous MOFs: (1) the amorphization of crystalline MOFs and (2) the direct synthesis. Special attention is paid to the relationship between preparation method, properties and applications of amorphous MOFs. We also explore the field of MOF liquids and their applications, centering our attention to the phenomenon of melting. Finally, MOF glasses are explained. We highlight the properties and applications of the MOF glasses that are not usually found in crystalline MOFs. New related glass materials such as MOF-blends, flux melted MOFs, MOF crystal-glass composites, MOF and inorganic glass composites, and MOF glass membranes are also reviewed. We conclude the fields of amorphous MOFs, MOF liquids, and MOF glasses by presenting our thoughts on the possible future research directions.

结晶度以外的金属有机框架（MOF）：无定形MOF，MOF液体和MOF玻璃

金属有机骨架（MOF）领域被错误地认为是纯晶体。但是，非晶MOF（非晶MOF，MOF液体和MOF玻璃）已开始作为替代材料出现，超出了晶体MOF的独占范围。非晶态MOF提供了许多机会，它们既可以作为新颖的功能材料本身使用，也可以作为制造其他材料的媒介。在这篇详尽的综述中，我们描述了两种制备非晶MOF的方法：（1）结晶MOF的非晶化和（2）直接合成。特别要注意非晶态MOF的制备方法，性质和应用之间的关系。我们还将探索MOF液体及其应用领域，将注意力集中在熔化现象上。最后，说明MOF眼镜。我们重点介绍了晶体MOF中通常不存在的MOF玻璃的特性和应用。还审查了新的相关玻璃材料，例如MOF混合物，熔剂熔融的MOF，MOF晶体玻璃复合材料，MOF和无机玻璃复合材料以及MOF玻璃膜。通过介绍我们对未来可能的研究方向的看法，我们总结了非晶态MOF，MOF液体和MOF玻璃的领域。
