A novel donor–acceptor–donor triad that exhibits fluorescence on–off switching with high contrast ratio (ca. 10 3 ) in response to a mechanical stimulus in the solid state is reported. This system provides a very unique example of high‐contrast fluorescence switching that is driven by a mechanical‐force‐controlled photo‐induced electron transfer (eT) in molecular assemblies.
