A new series of red phosphorescent iridium(lll) complexes, (PT‐MQ) 2 Ir(tmd), (PT‐P) 2 Ir(tmd), and (PT‐TFP) 2 Ir(tmd) were synthesized for highly efficient red emitter of the organic light‐emitting diodes (OLEDs). The devices give very deep red EL spectra with much narrower full width at half maximum (FWHM). Maximum current efficiency of devices is 8.56 Cd/A, 5.52 Cd/A, and 2.62 Cd/A respectively.
