The novel green dopants based on BODIPY and two different arylamine moieties, namely 9-phenylcarbazole and triphenylamine, have been successfully synthesized and characterized. Due to possessing the similar photophysical properties of these materials, the compound containing 9-phenylcarbazole moiety has been used as a standard for fabricating the OLED device with the structure of ITO/NPB/BODIPY (3 wt% in Alq3)/Alq3/LiF/Al. This device showed good performance with low turn on voltage (3.0 V), green emission (CIE = 0.40, 0.57), maximum brightness, current efficiency and power efficiency of 30,000 cd/m2, 4.32 cd/A, and 5.43 lm/W, respectively. |
