A [2]Rotaxane Flip Switch Driven by Coordination Geometry

摘要

A molecular switch that is derived from a mechanically interlocked molecule (MIM) can exist in two distinct molecular arrangements: the ground-state co-conformation (GSCC) and a metastable co-conformation (MSCC), which are in equilibrium.'11 Ideally, these co-conformers are easily identifiable by using a spectroscopic technique, their relative populations are quantifiable, and the position of the equilibrium can be controlled by some external perturbation.
