Electrochemical investigations showed a side reaction takes place inside an active layer which diminished the overall device efficiency. By using a dopant and host active layer architecture, the formation of the by product was removed. The by-product was identified as a σ-dimer formed inside an oligomer. The active layers were investigated by electrochemical techniques (cyclic voltammetry, UV-Vis-NIR spectroelectrochemistry, Electron Paramagnetic Resonance (EPR) spectroelectrochemistry and Dynamic Electrochemical Impedance Spectroscopy (DEIS)) to characterize the layers, charge carriers, and electronic energy levels. It is clear from these observations that electrochemical reactions of emitter molecules in a working devices is a route to device degradation. © 2015 Published by Elsevier Ltd.}, author_keywords={Conjugated polymers; Degradation; Molecular electronics; OLED; σ-Dimers}, keywords={Conjugated polymers; Cyclic voltammetry; Degradation; Dimers; Electron spin resonance spectroscopy; Light emitting diodes; Magnetic resonance; Molecular electronics; Molecules; Organic light emitting diodes (OLED); Paramagnetic resonance; Spectroelectrochemistry, Dynamic electrochemical impedance spectroscopy; Electrochemical degradation; Electrochemical investigations; Electrochemical reactions; Electrochemical techniques; Electron paramagnetic resonances (EPR); Electronic energy levels; OLED, Electrochemical impedance spectroscopy}, funding_details={Engineering and Physical Sciences Research CouncilEngineering and Physical Sciences Research Council, EPSRC, EP/K016164/1}, references={Adachi, C., Baldo, M.A., Thompson, M.E., Forrest, S.R., Nearly 100% internal phosphorescence efficiency in an organic light-emitting device (2001) J.
