Abstract:
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.
