| 英文摘要 | Phosphorescent copper(I) complexes show great promise as emitters in organic light-emitting diodes (OLEDs). However, most copper(I) complexes are neither soluble nor stable toward sublimation and, hence, not amenable to the typical methods to fabricate OLEDs. In this work, a compound 3-(carbazol-9-yl)-5-((3-carbazol-9-yl)phenyl)pyridine (CPPyC) was designed as both a good ligand and host matrix. Codeposition of CPPyC and copper iodide (Cul) gives luminescent films with photoluminescent quantum yields (PLQY) as high as 100%. A dimeric copper(1) complex Cu2I2(CPPyC)(4) is formed in the thin film, characterized by X-ray absorption spectroscopy. A series of simple, highly efficient green-emitting OLEDs were demonstrated by using the codeposited film as an emissive layer. A device comprised of only CPPyC and Cul gave an external quantum efficiency (EQE) of 12.6% (42.3 cd/A) at 100 cd/m(2), while a device with tailored hole and electron transporting layers gave an efficiency of 15.7% (51.6 cd/A) at the same brightness. |
