                 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).
