The electrochromic properties of dithienylethene derivatives is a field of great importance and interest. In this manuscript the authors describe a potential mol. remote control system, which can be electrochem. triggered. Diferrocenyl compounds containing a diethylenene photoelectrochromic core with perhydro- and perfluorocyclopentene ring were prepared to induce a change in the chromic properties via an intramol. electron-transfer reaction from the redox group to the photochromic core. The electrochem. behavior of open and closed isomers was thoroughly studied using photochem., electrochem., and spectroelectrochem. techniques. The 1st redox couple was typically assigned to the ferrocene for the open isomer. However, for the closed isomer, an electrocatalytic ring-opening process was observed for the perhydrocyclopentene ring, while a slightly different electrochem. process was observed for the perfluorocyclopentene system. Mechanistic studies revealed that an internal charge transfer is necessary to destabilize the closed bridge. Once opened, the bridge’s cation radical is a strong oxidant, and the charge eventually gets localized on the ferrocene. The charges then migrate throughout the solution by self-exchange reactions. Hence, the redox status of the Fc units triggers the photochrom’s reactivity playing the role of antenna that can temporarily store a charge and facilitate the transformation. This way to perform the transformation, i.e., by electrochem. rather than photochem., presents the great advantage of being much more local and, thus, would permit the ultimate stage of miniaturization at the scale of just one ol.
