✦ Synopsis

acetylacetone (5.0 mmol) and Na 2 CO 3 (10.0 mmol) were mixed with 2-ethoxyethanol (15 mL) and the mixture was refluxed at 100 C under a nitrogen atmosphere for 12 h. After cooling to room temperature, 2-ethoxyethanol was removed by vacuum. The residue was dissolved in dichloromethane and the solid was filtered off. The solution was concentrated in vacuo and the residue was purified on a silica gel column using dichoromethane and hexanes as eluent to give the desired iridium complex [Ir(PEQ) 2 (acac)]. The product was then sublimated at 200±220 C and at 4 10 ±3 Pa prior to device fabrication. Similar procedures were also employed for the synthesis of other iridium complexes (MPEQ) 2 Ir(acac) and (PEIQ) 2 Ir(acac). The spectral data and yields of all iridium complexes are as follows.

(PEQ) 2 Ir(acac):
