constructed through a stepwise bottom-up synthesis. The belt [6]cyclothianthrene ([6]CT) is the smallest and most strained member of the family yet reported. Both [6]CT and [8]CT are the first examples of cyclothianthrene characterized by single crystal X-ray diffraction. An unprecedented chiral belt [7]CT and a Möbius-shaped [9]CT were also achieved via modular synthesis. Crystallographic and computational
环硫蒽是十年前提出的一系列含硫烃带,通过逐步自下而上的合成成功构建。带 [6] 环噻蒽 ([6] CT ) 是该家族中最小和最紧张的成员。[6] CT和 [8] CT都是通过单晶 X 射线衍射表征的环噻蒽的第一个例子。还通过模块化合成实现了前所未有的手性带 [7] CT和莫比乌斯形 [9] CT。晶体学和计算研究表明,带 [6] CT- [8] CT具有棱柱状构象,具有明确定义的管状腔,具有包含客体分子的潜力。循环伏安图进一步显示这些带具有氧化还原活性。构建含硫烃带,即环噻蒽的成功极大地丰富了杂原子掺杂分子带和管的化学性质。
