thiacalix[4]-2,8-thianthrene (TC[4]TT), was successfully prepared from a cyclo-p-phenylenesulfide derivative using acid-induced intramolecular condensation. Single crystal X-ray diffraction revealed that TC[4]TT adopts an alternative octagonal form recessed to the inner side. Its internal cavity included small solvents, such as chloroform and carbon disulfide. Due to its polygonal geometry, TC[4]TT laminated
含硫大环化合物因其多边形环状骨架而表现出独特的特性,因此引起了人们的极大兴趣。在这项研究中,利用酸诱导的分子内缩合,成功地从环对苯硫醚衍生物制备了带有硫连接基的噻蒽基环状四聚体,thiacalix[4]-2,8-噻蒽醌(TC[4]TT)。 。单晶X射线衍射表明TC[4]TT采用向内侧凹进的替代八角形形式。其内腔包含小溶剂,例如氯仿和二硫化碳。由于其多边形几何形状,TC[4]TT 层压成具有多孔通道的蜂窝状图案。此外,TC[4]TT 在环境温度和液氮温度下的 CH2Cl2 溶液中显示出荧光和磷光发射。与参考化合物(二(山蒽-2-基)硫烷(TT2S)和噻蒽(TT))相比,两个发射带均略有红移。这项工作描述了一种基于含硫硫杂环杂环的大环系统,具有基于分子平铺和溶液中光物理性质的有趣的超分子化学。
