We report on the overall improvement of a single layer organic light-emitting diode device based on poly{[3-hethylthiophene]- co-3-[2-(p-cyano-phenoxy)ethyl]thiophene} or namely PTOPhCN. This polymer was recently developed by adding a cyano group as a side-chain substituent of the thiophenic backbone onto the main polymer chain and showed promising results for light-emitting diode devices. Using an improved device layout, bright red electroluminescence was obtained at 4 V and showed a luminance of about 400 cd/m2 at 8 V with current densities in the order of 6000 A/m2.
