Abstract

Abstract : The π-conjugation of an electroactive perchlorotriphenylmethyl (PTM˙) radical to an E / Z switchable stilbene derivative permits to demonstrate that its electrocatalytic Z → E isomerization is undoubtedly triggered by the open-shell nature of PTM˙ unit. Abstract : A push–pull-functionalized stilbene has been prepared, with an electroactive perchlorotriphenylmethyl (PTM˙) radical and dimethylamine units as electron-withdrawing and -donating moieties, respectively, showing an electrocatalytic redox-induced Z → E isomerization where the open-shell nature of PTM˙ plays a key role in the isomerization ocurrance.
