In contrast, adsorptive separation using porous materials has emerged as a promising alternative, presenting substantial potential for energy savings and improved operational efficiency. Among these materials, metal–organic frameworks (MOFs) have garnered considerable attention due to their unique structural and functional characteristics. MOFs are a class of crystalline porous materials constructed from inorganic metal ions or clusters connected by organic linkers through strong coordination bonds. Their precisely engineered architectures create well-defined nanoscale spaces capable of selectively trapping guest molecules. In contrast to traditional porous materials such as zeolites and activated carbons, emerging MOFs not only demonstrate exceptional capabilities for pore regulation and interior modification through nanospace engineering but also hold great promise as a superior platform for the development of high-performance functional materials. By virtue of the isoreticular principle and building unit assembly strategies in MOF chemistry, precise adjustments to pore structures─including pore size, shape, and surface chemistry─can be readily achieved, making them well-suited for addressing the separation of intractable industrial gas mixtures, particularly those with similar sizes and physicochemical properties.","PeriodicalId":72040,"journal":{"name":"Accounts of materials research","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, the most typical cycloarene, kekulene, was expected to provide a crucial experimental test to determine whether π-electrons are delocalized over the entire molecule or delocalized at the benzenoid rings. This question has captivated synthetic chemists for decades. After numerous failed attempts, Staab and Diederich achieved the first conclusive synthesis of kekulene in 1978. The deshielded inner protons in the <sup>1</sup>H NMR spectrum conclusively demonstrated that the π-electrons in cycloarenes are delocalized at individual benzenoid rings.
