Abstract

A new blue phosphorescent iridium(Ⅲ) complex based on 2'

6'-difluoro-2

3'-bipyridine and 3-Acetyl-camphor

(dfpypy)

Ir(acam) was synthesized. The complex emits bright blue phosphorescence with

max

at 466 nm accompanied a weakly shoulder peak at 487 nm and has the full-width at half maximum (FWHM) of 55 nm. The photoluminescence (PL) quantum yield in degassed THF solution at room temperature is estimated to be 0.51. The efficient non-doped blue phosphorescent electroluminescence devices were fabricated. The structure of devices is ITO/HATCN(1 nm)/TAPC(40 nm)/(dfpypy)

Ir(acam) (10 nm)/BmpypB (40 nm)/LiF(1 nm)/Al(90 nm). The devices show electroluminescence with

max

at 474 nm. The devices have

value of 3.5 V. At a current density of 20 mAcm

-2

CIE coordinates are (0.17

0.29). Maximum brightness of 2 170 cdm

-2

is achieved at driven voltage of 11 V. At driven voltage of 4.2 V

maximum power efficiency of 5.25 lmW

-1

and maximum luminance efficiency of 6.45 cdA

-1

are obtained

respectively.
