The exploitation of new materials for adsorptive separation of industrially important hydrocarbons is of great importance in both scientific research and petrochemical industry. Nonporous adaptive crystals (NACs) as a robust class of synthetic materials have drawn much attention during the past five years for their superior performance in adsorption and separation. Pillararenes are the main family of macrocyclic arenes used for NACs construction, where the structure-function relationship has been intensively studied. In the past two years, some emerging types of synthetic macrocyclic arenes have been successfully brought into this research field, showing the gradual enrichment and diversification of NACs materials. This Minireview summarizes the recent advances of synthetic macrocycle-based NACs, which are categorized by various practical applications in molecular separation. Besides, NACs-based vapochromic supramolecular systems are also discussed. Finally, future perspectives and challenges of NACs are given. We envisage that this Minireview will be a useful and timely reference for those who are interested in new molecular and supramolecular crystals for storage and separation applications.
开发用于吸附分离具有工业重要性的碳氢化合物的新材料，在科学研究和石化工业中都具有重要意义。无孔自适应晶体（NACs）作为一类坚固的合成材料，在过去五年中因其在吸附和分离方面的卓越性能而备受关注。柱芳烃是用于构建NACs的主要大环芳烃家族，其结构-功能关系已得到深入研究。在过去两年中，一些新兴类型的合成大环芳烃已成功进入该研究领域，显示出NACs材料的逐渐丰富和多样化。本综述总结了基于合成大环的NACs的最新进展，这些进展按分子分离中的各种实际应用进行分类。此外，还讨论了基于NACs的气相变色超分子体系。最后，给出了NACs的未来前景和挑战。我们设想，本综述将为那些对用于存储和分离应用的新型分子和超分子晶体感兴趣的人提供有用且及时的参考。
