Unusual Electrochemical Properties of the Electropolymerized Thin Layer Based on a s-Tetrazine-Triphenylamine Monomer

In this work the electrochemical and spectroelectrochemical characterization of a s-tetrazine-triphenylamine derivative with a donor–acceptor–donor-type structure is reported, which in addition undergoes electrochemical polymerization. The investigations of the polymerized layers have revealed unusual characteristics. Thin polymeric film exhibits charge-trapping properties with great storage and memory effect. Moreover, the polymer displays reversible switching of fluorescence in oxidation mode and emission of light during reduction.
