Abstract

Phosphorescent materials, IR-FPPA1, IR-PPA1 and IR-TPA1 as emission dopants for electroluminescent (EL) devices were synthesized. Three types of devices such as ITO/ NPD/IR-FPPA1 (6%), IR-PPA1 (6%) and IR-TPA1 (6%) in CBP/BCP/Alq/LiF/Al were fabricated. IR-FPPA1, IR-PPA1 and IR-TPA1 exhibited 540 Cd/m2, 6600 Cd/m2 and 590 Cd/m2 with their external quantum efficiency of 1.2%, 8.9% and 3.0% in current densities of 20 mA/cm2, respectively. EL spectra of the IR-FPPA1, IR-PPA1, and IR-TPA1 devices had the band maxima at 490 nm, 535 nm and 615 nm, respectively.
