Abstract: Three kinds of green light-emitting iridium complexes (Ⅲ,Ⅳ,Ⅴ) were designed and synthesized
using 5-methyl-2-phenylpridine (CH 3ppy) as main ligand, 3,7-diethyl-4,6-nonanedione (detd), 2,2,6,6-
tetramethyl-3,5-heptanedione(tmd)and acetylacetone (acac) as three ancillary ligands (LX), respectively.

These compounds were characterized by HNMR, elemental analysis. The maximum absorption
wavelengths of compounds Ⅲ, Ⅳ and Ⅴ measured by UV-Vis spectrum were between 250 and 280 nm,
and the maximum emission wavelengths of compound Ⅲ, Ⅳ and Ⅴ measured by fluorescence emission
spectrum (PL) were 530.8, 534.2 and 524.8 nm. Phosphorescent organic light-emitting diodes with the
prepared complexes were constructed. Three organic light emitting diodes were prepared in this paper. The
device based on compound Ⅲ exhibits the best overall performance in three devices. It has a brightness of
2
59125 cd/m . In addition, it shows a maximum external quantum efficiency of 15.0%, a maximum current
efficiency of 53.8 cd/A, and a maximum power efficiency of 62.1 lm/W with chromaticity coordinates
CIE(x,y)=(0.30,0.62).
