Polymer‐based white‐light‐emitting diodes are fabricated using conjugated oligoelec trolytes as effective electron‐injection layers. However, the choice of solvent used to deposit the conjugated oligoelectrolyte bears a strong influence on the final composition of the emissive layer. Inclusion of water decreases the contact with hydrophobic underlying coatings, and minimizes the extraction of one of the molecular components required for function.
