title: Efficient phosphorescent green and red organic light-emitting diodes based on the novel carbazole-type host material.
abstract: We developed a novel carbazole-type material, 9-phenyl-3,6-bis(4-(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl)-9H-carbazole (LPGH 153), and fabricated the green and red phosphorescent organic light-emitting diodes (OLEDs) using LPGH 153 as host. The red and green devices have the max. luminous efficiencies of 22.2 cd/A and 32.2 cd/A, respectively.
