A Two‐Stage Molecular Retractable Cable Featuring Push‐Button and Rotary Two‐Way Switching Modes

Abstract

A molecular cage based [2]rotaxane is reported in which the linear thread component can be elongated and contracted in a stepwise manner, mimicking a two-stage retractable cable that can be operated in both push-button (free-selection) and rotary (continuous-change) modes, depending on the choice of reagents.
