摘要：

We report that by applying an electric field to a single squaraine-derived rotaxane (SR) molecule on bare glass, the fluorescence can be completely quenched. The molecule undergoes a reversible fluorescence switch between a zero-field "on'' state and a high-field "off'' state, which is attributed to intramolecular electron transfer within the SR molecule.
