| 摘 要： | 合成了一种含苯并噻唑结构配体的环金属化铱配合物(ffbi)2Ir(acac)，(其中ffbi为1-(4-氟苄基)-2-(4-氟苯基)苯并咪唑，acac为乙酰丙酮)，并以其作为发光体, 制备了有机电致发光器件。结果表明该配合物具有强磷光发光特性，器件发绿色光。其中结构为TCTA(40 nm)/CBP∶Ir(6.3%，30 nm)/BCP(10 nm)/Alq(40 nm)的电致发光器件在12 V电压下最大发光亮度达41 499 cd·m-2，在8 V电压下，最大外量子效率达5.7%。 |

| Abstract: | A bis-cyclometalated iridium complex(ffbi)2Ir(acac)(ffbi=l-(4-fluorobenzyl)-2-(4-fluorophenyl)benzimidazole,acac=acetylacetone)containing benzimidazole-based ligand has been synthesized and used as an emitter in organic light emitting diodes(OLEDs).The results showed that this complex had a strong phosphorescent character and the EL devices based on this complex emitted green light.For the device with the structure of TCTA(40nm)/CBP:Ir(6.3%,30nm)/BCP(10nm)/Alq(40nm),the maximum brightness reached 41499 cd·m-2 at a voltage of 12 V and the maximum external efficiency reached 5.7%at a voltage of 8 V. |
