PTTCN can crystallize into two kinds of crystals with different fluorescence colors in different solvent systems. The molecules in two crystals are in different stereo isomeric forms of nitrogen, quasi axial (\n                    <jats:italic>ax<\/jats:italic>\n                    ), and quasi equatorial (\n                    <jats:italic>eq<\/jats:italic>\n                    ). The crystals with blue fluorescence in\n                    <jats:italic>ax<\/jats:italic>\n                    form may selectively adsorb benzene by a single\u2010crystal\u2010to\u2010single\u2010crystal (SCSC) transformation, but separated benzene from a benzene\/cyclohexane equimolar mixture with a low purity of 79.6%. Interestingly, PTTCN molecules with\n                    <jats:italic>eq<\/jats:italic>\n                    form and benzene co\u2010assembled to construct a hydrogen\u2010bonded framework (X\u2010HOF\u20104) with S\u2010type solvent channels and yellow\u2010green fluorescence, and can release benzene to form nonporous guest\u2010free crystal under heating. Such nonporous crystals strongly favor aromatic benzene over cyclohexane and may selectively reabsorb benzene from benzene\/cyclohexane equimolar mixture to recover original framework, and the purity of benzene can reach \u224896.5% after release from framework. Moreover, reversible transformation between the nonporous crystals and the guest\u2010containing crystals allows the material to be reused.\n                  <\/jats:p>","DOI":"10.1002\/smll.202304340","type":"journal-article","created":{"date-parts":[[2023,6,16]],"date-time":"2023-06-16T01:53:19Z","timestamp":1686880399000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["Flexible Luminescent Hydrogen\u2010bonded Organic Framework for the Separation of Benzene and Cyclohexane"],"prefix":"10.1002","volume":"19","author":[{"given":"Meng","family":"Liang","sequence":"first","affiliation":[{"name":"Tianjin Key Laboratory of Structure and Performance for Functional Molecules College of Chemistry Tianjin Normal University  No. 393, Binshui West Road Tianjin 300387 P.
