by silica gel column chromatography chloroform hexane 1 3 to obtain 3 32 g of 1 phenyl isoquinoline yield 90 900 mg of 1 phenyl isoquinoline 4 4 mmol and 947 8 mg of na 3 ircl 6 3h 2 o 2 0 mmol were added into 100 ml of reaction bowl and 30 ml of 2 ethoxy ethanol as distilled solvent was added thereto under the flow of nitrogen and then the reaction was performed in reflux at 110 u00b0 c for 12 hr the mixture was cooled to room temperature and 15 ml of distilled water was added thereto and the precipitate obtained therefrom was filtered through glass filter of g4 size washed with 15 ml of methanol and 15 ml of ethyl ether and dried to obtain a precursor of iridium complex compound 900 0 mg of the precursor of iridium complex compound 0 7 mmol prepared in the above 1 step 198 mg of tri acetyl methane 1 4 mmol and 100 mg of k 2 co 3 were added into 50 ml of reaction bowl and 30 ml of 2 ethoxy ethanol as distilled solvent was added thereto under the flow of nitrogen and then the reaction was performed in reflux at 110 u00b0 c the mixture was cooled to room temperature and the precipitate obtained therefrom was filtered through glass filter of g4 size washed with 15 ml of methanol and collected the above synthesized materials were further purified and sublimed with a vacuum sublimation apparatus to use for organic el device and then the molecular structure of material obtained thereby was analyzed by nmr and mass spectroscopy as a result it was.
