host : guest complexes with aniline, N-methylaniline, and N,N-dimethylaniline when recrystallized from these solvents. When the guests competed, as in binary and ternary mixtures, DMT proved to be remarkably selective for the alkylated guests, discriminating consistently against aniline. A host selectivity order of aniline << N-methylaniline < N,N-dimethylaniline was observed. Results from single-crystal diffraction
化合物(–)-(2 R,3 R)-2,3-二甲氧基-1,1,4,4-四苯基丁烷-1,4-二醇(DMT)形成2:1宿主:客体与苯胺,N -甲基苯胺和N,N-二甲基苯胺从这些溶剂中重结晶时。当宾客竞争时(如二元和三元混合物),事实证明,DMT对烷基化宾客具有显着的选择性,始终与苯胺区分开。苯胺<< N-甲基苯胺< N,N的主体选择性顺序观察到-二甲基苯胺。单晶衍射,Hirshfeld表面和热分析的结果用于解释观察到的偏好顺序。这项研究表明,利用超分子化学领域在这些苯胺的分离中可能具有未来的应用。
