| Electrical characterization of anionic poly(terphenylenevinylene) (PTPVa) furthered understanding of ionically functionalized conjugated polymers and their potential for use as a light emitting electrochemical cell (LEC). The undoped PTPVa film was determined to have a low conductivity by solid-state current-voltage measurements. However, p-doping of an interdigitated electrode device at 0.5 V increased conductivity of the polymer by 20.3x. P-doping of an interdigitated electrode device at 1.2 V increased conductivity of the polymer by 583x. P-doping was determined to peak at 1.23 V vs. Ag/Ag+ reference electrode by cyclic voltammetry. |
