Abstract

The preparation and characterization of a solvent-switchable rotaxane that shuttles in the opposite direction to that expected are reported. The reverse shuttling is confirmed by NMR spectroscopy and can be monitored by cyclic voltammetry. The electrochemically generated anions on the fullerene moiety are stabilized by the closer proximity of the macrocycle.

摘要

报道了一种溶剂可切换轮烷的制备与表征，该轮烷的穿梭方向与预期相反。通过核磁共振光谱证实了反向穿梭，并且可以通过循环伏安法进行监测。富勒烯部分上通过电化学产生的阴离子因大环更靠近而得以稳定。
