  An Electrochemically Controllable Nanomechanical Molecular System Utilizing Edge-to-Face and Face-to-Face Aromatic Interactions

  摘要：

  [GRAPHICS]A new molecular system, 2,11-dithio[4,4]metametaquinocyclophane containing a quinone moiety; was designed and synthesized. As the quinone moiety can readily be converted into an aromatic pi-system (hydroquinone) upon reduction, the nanomechanical molecular cyclophane system exhibits a large flapping motion like a molecular flipper from the electrochemical redox process. The conformational changes upon reduction and oxidation are caused by changes of nonbonding interaction forces (devoid of bond formation/breaking) from the edge-to-face to face-to-face aromatic interactions and vice versa, respectively.

  层状化合物。六。[3.3] 环烷烃和相关环烷烃的简便合成和光谱性质

  摘要：

  介绍了一种通过二硫杂 [4.4] 环烷合成 [3.3] 环烷的简单方法。检查了各种环芳烃的光谱，并与 [2.2] 类似物的光谱进行了比较。从吸收光谱得出结论，环芳的跨环 π-π 相互作用强烈依赖于环到环的距离和重叠模式。从发射光谱可以看出，平行夹心型的环芳很容易形成正态准分子，而[2.2] 间环芳和[2.2]-和[3.3] 间对环芳形成应变的准分子，显示出明显的荧光带红移。
