24_40/2012Piezochromism: Unique Piezochromic Fluorescence Behavior of Dicyanodistyrylbenzene Based Donor–Acceptor–Donor Triad: Mechanically Controlled Photo-Induced Electron Transfer (eT) in Molecular Assemblies (Adv. Mater. 40/2012)

A donor–acceptor–donor triad, which exhibits fluorescence on-off switching with high contrast ratio (ca. 1000) in response to mechanical stimulus in the solid state, is reported by Soo Young Park and co-workers on page 5487. 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.
