- Abstract
- A novel donor-acceptor-donor triad that exhibits fluorescence on-off switching with high contrast ratio (ca. 103) 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.
