Solution processable red iridium dendrimers containing oligocarbazole dendrons for efficient nondoped and doped phosphorescent OLEDs

Solution processable red Ir dendrimers have been demonstrated to give state-of-art current efficiencies as high as 9.2 and 25.7 cd A ⁻¹ for nondoped and doped PhOLEDs, respectively, which can compete well with vacuum-deposited small molecular phosphors.
