Abstract

•Phosphorescent anionic Ir(III) complex investigated as emitter for light-emitting electrochemical cells.•Investigation of the device configuration to enhance the device performance.•Introduction of a PVK layer in LEC to avoid pinholes.•Determination of the device lifetime at different applied voltage.•Heteroleptic complex characterized by UV–vis and luminescence spectroscopy.

The optical and electronic properties of a solution-processed light-emitting electrochemical cell (LEC) based on an anionic iridium (III) complex as the emitter material has been designed and investigated. The obtained multi-layered devices emitted light of a light-green color (CIE, x = 0.29, y = 0.45) at low external applied voltage. The electroluminescent devices fabricated from this anionic iridium complex exhibited a relatively moderate electroluminescent efficiency and a luminance as high as 140 cd/m2 at 7.2 V.
