3 [(DFMPPZ)

Ir(CN)(PPh

and 4 [(DPPF)

Ir(acac)] were synthesized

where DFMPPZ= 2-(2

4-difluorophenyl)- 3-methylpyrazine

pic=picolinate

Ph=phenyl

acac=acetylacetonate

MDPPF=4

4'-difluoro-5-methyl-2

3- diphenylpyrazine. The complexes were characterized by mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy. Their photophysical properties were investigated by UV-Vis and photoluminescence (PL) spectroscopy. All of these Ir (Ⅲ) complexes show the noticeable absorption peaks from metal-to-ligand charge transfer (MLCT) transitions. The iridium (Ⅲ) complexes 1

3 and 4 have strong photoluminescence at 528

536

535 and 561 nm

respectively. Moreover

the iridium (Ⅲ) complex 4 was utilized as phosphorescence dopant in OLEDs with the structures of ITO/MoO

(1 nm)/CBP(35 nm)/CBP:Ir(15 nm)/TPBi(50 nm)/LiF(1nm)/Al(100 nm). The devices showed yellow emission at 567 nm with a maximum brightness of 32 110 cdm
