Synthesis and assessment of compounds trans-N,N′-bis(9-phenyl-9-xanthenyl)cyclohexane-1,4-diamine and trans-N,N′-bis(9-phenyl-9-thioxanthenyl)cyclohexane-1,4-diamine as hosts for potential xylene and ethylbenzene guests

two novel compounds, trans-N,N′-bis(9-phenyl-9-xanthenyl)cyclohexane-1,4-diamine 1 and trans-N,N′-bis(9-phenyl-9-thioxanthenyl)cyclohexane-1,4-diamine 2, were designed and successfully synthesized in our laboratories, and assessed for their host potential in the presence of potential xylene (Xy) isomer and ethylbenzene (EB) guests. Host 1 successfully formed complexes with all four of o-Xy, m-Xy, p-Xy
在这项工作中,两种新型化合物,反式-N,N'-双(9-苯基-9-氧杂蒽基)环己烷-1,4-二胺 1 和反式-N,N'-双(9-苯基-9-硫杂蒽基) )环己烷-1,4-二胺 2 在我们的实验室中设计并成功合成,并在潜在的二甲苯 (Xy) 异构体和乙苯 (EB) 客体存在下评估了它们的主体潜力。宿主 1 成功地与所有四种 o-Xy、m-Xy、p-Xy 和 EB 形成复合物,而 2 只包合 p-Xy 和 EB。等摩尔客人/客人竞争实验表明,宿主 1 和 2 对这些客人具有非常相似的选择性 [p-Xy (73.9%) > EB (13.0%) > m-Xy (8.1%) > o-Xy (5.0%) 和p-Xy (71.3%) > EB (20.2%) > m-Xy (6.0%) > o-Xy (2.5%) 分别为 1 和 2]。单晶衍射分析揭示了硫主体类似物的显着几何变化:当客体不存在或存在时,氧
