Porous coordination polymers or metal-organic frameworks with reversible phase-transition behavior possess some attractive properties, and can respond to external stimuli, including physical and chemical stimuli, in a dynamic fashion. Their phase transitions can be triggered by adsorption/desorption of guest molecules, temperature changes, high pressure, light irradiation, and electric fields; these mainly include two types of transitions: crystal-amorphous and crystal-crystal transitions. These types of porous coordination polymers have received much attention because of their interesting properties and potential applications. Herein, reversible phase transition porous coordination polymers are summarized and classified based on different stimuli sources. Corresponding typical examples are then introduced. Finally, examples of their applications in gas separation, chemical sensors, guest molecule encapsulation, and energy storage are also presented.
具有可逆相变行为的多孔配位聚合物或金属有机框架具有一些吸引人的特性，并且能够以动态方式响应包括物理和化学刺激在内的外部刺激。它们的相变可以由客体分子的吸附/解吸、温度变化、高压、光照和电场触发；这些主要包括两种类型的转变：晶体-非晶态转变和晶体-晶体转变。由于其有趣的性质和潜在的应用，这类多孔配位聚合物受到了广泛关注。在此，基于不同的刺激源对可逆相变多孔配位聚合物进行了总结和分类。然后介绍了相应的典型例子。最后，还展示了它们在气体分离、化学传感器、客体分子封装和能量存储方面的应用实例。
