The first examples of optically pure 9H‐quinolino[3,2,1‐k]phenothiazine (QPTZ)‐based molecules are reported. The inversion of the nitrogen atom, locked in the QPTZ fragment, is confined with a high‐energy barrier that has allowed the isolation at room temperature of each stereoisomer. Considering the growing necessity in molecular electronics to introduce chiral characteristics within highly efficient
报道了基于光学纯的9H-喹啉[3,2,1-k]吩噻嗪(QPTZ)分子的第一个例子。锁定在QPTZ片段中的氮原子的转化受限于高能垒,该能垒允许在室温下分离每种立体异构体。考虑到分子电子学越来越需要在高效分子片段中引入手性特征,提供了一种在非常有前途的富电子核心QPTZ上构建对映体纯衍生物的分子策略。由于这项工作旨在报告QPTZ手性的基础,因此本研究结果可能会为使用该片段的光学纯净形式开辟道路。
