Vapochromic materials, which undergo colour and/or emission changes upon exposure to certain vapours or gases, have received increasing attention recently because of their wide range of applications in, e.g., chemical sensors, light-emitting diodes, and environmental monitors. Vapochromic crystals, as a specific kind of vapochromic materials, can be investigated from the perspective of crystal engineering to understand the mechanism of vapochromism. Moreover, understanding the vapochromism mechanism will be beneficial to design and prepare task-specific vapochromic crystals as one kind of low-cost 'electronic nose' to detect toxic gases or volatile organic compounds. This review provides important information in a broad scientific context to develop new vapochromic materials, which covers organometallic or coordination complexes and organic crystals, as well as the different mechanisms of the related vapochromic behaviour. In addition, recent examples of supramolecular vapochromic crystals and metal-organic-framework (MOFs) vapochromic crystals are introduced.

气相致变色晶体：从晶体工程的角度了解气相致变色。

由于暴露于某些蒸气或气体中而发生颜色和/或发射变化的气相致变色材料由于其在例如化学传感器，发光二极管和环境监测器中的广泛应用而受到越来越多的关注。可以从晶体工程的角度研究气相致变色晶体作为一种特定的气相致变色材料，以了解气相致变色的机理。此外，了解气相致变色机理将有助于设计和制备特定于任务的气相致变色晶体，将其作为一种低成本的“电子鼻”来检测有毒气体或挥发性有机化合物。这篇评论为广泛的科学背景提供了重要信息，以开发新的气相致变色材料，它涵盖了有机金属或配位化合物和有机晶体，以及相关的气相致变色行为的不同机理。另外，介绍了超分子气相致变色晶体和金属有机骨架（MOF）气相致变色晶体的最新实例。
