Charge trapping in poly(1-amino-anthraquinone) films

► Anodic electrochemical polymerization of 1-amino-anthraquinone produces a polymer with complex electrochemistry. ► Voltammetry shows features due to both a polyaniline-like backbone and the quinone/hydroquinone couple. ► Reduction of the quinone groups results in metastable trapping of the reduced state. ► Impedance measurements have shown that charge trapping results from the low conductivity of the reduced polyaniline-like backbone.
