Design of blue or yellow emitting devices controlled by the deposition process of a cationic iridium (III) complex

► Phosphorescent Ir(III) complex investigated as emitter for light-emitting electrochemical cells and polymer organic light-emitting diodes. ► Exploration of the deposition conditions of the emissive layer in multilayered electroluminescent devices. ► Impact of the deposition process of the complex in the emitted color. ► Both strategies of deposition enabled to produce blue or yellow emitting devices. ► Heteroleptic complex characterized by UV-visible and luminescence spectroscopy, cyclic voltammetry and DFT calculations.
