Abstract:
In this paper, we report a phosphorescent Ir(III) emitter of Ir(acac-F6)(F-BT)(2), where acac-F6 = 1,1,1,5,5,5-hexafluoropentane-2,4-dione and F-BT = 2-(2-fluorophenyl)benzo[d]thiazole, including its crystal structure, electronic nature, photophysical characteristics, thermal and electrochemical properties. Data suggest that Ir(acac-F6)(F-BT)(2) is a promising emitter with high quantum yield of 0.19 and good thermal stability, along with its proper energy levels for charge carrier transportation. Electroluminescence (EL) devices using Ir(acac-F6)(F-BT)(2) as emitter are also fabricated, and their electroluminescence performances are investigated in detail. The optimal EL device shows a maximum luminance of 27,000 cd/cm(2) and a peak current efficiency of 8.7 cd/A.
