| 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=1-(4-fluorobenzyl)-2-(4-fluorophenyl)benzimid-azole, 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(40 nm)/CBP∶Ir(6.3%, 30 nm)/BCP(10 nm)/Alq(40 nm), the maximum brightness reached 41 499 cd·m-2 at a voltage of 12 V and the maximum external efficiency reached 5.7% at a voltage of 8 V. |
