A thiophene‐phenylquinoline‐based homoleptic Ir III complex, [Ir(Th‐PQ) 3 ], has been synthesised by a simple route and utilised as a dopant in solution‐processed phosphorescent organic light‐emitting diodes (PhOLEDs). It shows the current efficiency of approximately 26 cd A −1 and the external quantum efficiency of about 21 %, which are the highest values reported to date for PhOLEDs prepared by solution‐process.
