摘要：We report the operation of a ferrocene-based bistable [1]rotaxane that can work in two parallel platforms. In an "active" signal mode, the relative mechanical movement of its ring and thread In response to external acid-base-stimuli can result in a remarkable fluorescence signal output observed by the naked eye, whereas no obvious fluorescence change occurred In a "silent" signal mode after oxidation. Its fluorescence responses to the different combinations of DBU and/or Fe(CIO4)(3) corresponds to an INHIBIT logic gate.
