چکیده انگلیسی
Low-cost bicarbazole-based hole transporting derivative with diphenylvinyl substitutions was synthesized by simple procedure and characterized. The respective glass transition temperature of the material was estimated to be 81â¯Â°C, which can provide morphologically-stable amorphous films for applications in organic light emitting diodes. The compound possesses an adequate ionization potential, suitable triplet energy and high hole drift mobility of 5.54â¯eV, 2,61â¯eV and of 2â¯Ãâ¯10â3â¯cm2/V·s, respectively, which make it a suitable hole transporting material for use in red phosphorescent organic light-emitting diodes. The respective peak efficiency of the red device with the p-type dopant was recorded at 8.3% (5.2â¯cd/A and 3.3 lm/W) and at 7.8% (4.9â¯cd/A and 1.9 lm/W) for 100â¯cd/m [2] brightness, demonstrating high potential of the material for applications in light emitting diodes. The characteristics indicated that device with the bicarbazole-based compound exhibited better performance than those of widely used 1,1-bis [(di-4-tolylamino)phenyl]cyclohexane (TAPC) -based device.
