Abstract

Abstract To construct a supramolecular mechanophore library, expanding the variety of emitters that can be used is significant. In this study, we demonstrate that 9-(phenylethynyl)-10-((2-pyridyl)ethynyl)anthracene can be incorporated into a rotaxane-based supramolecular mechanophore as the luminophore. The polyurethane films in which the mechanophore was covalently incorporated exhibit instantly reversible on/off switches of green fluorescence upon cycle stretching.
