Unique Piezochromic Fluorescence Behavior of Dicyanodistyrylbenzene Based Donor-Acceptor-Donor Triad: Mechanically Controlled Photo-Induced Electron Transfer (eT) in Molecular Assemblies
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‐for...

Zusammenfassung: | 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. |
