Organometallic compound and organic light-emitting device including the same
摘要
說明書
2.15 g (6.6 mmol) of Intermediate L1 and 1.11 g (3.1 mmol) of iridium chloride were mixed with 40 mL of ethoxyethanol and 15 mL of distilled water, and then heated under reflux for 24 hours. After the reaction was completed, the temperature was lowered to room temperature to obtain a solid product. This solid product was filtered and then washed sufficiently with water, methanol, and then hexane. The obtained solid was dried in a vacuum oven to obtain 2.54 g of Intermediate L1 Dimer.
Synthesis of Compound 1
2.54 g (1.45 mmol) of Intermediate L1 Dimer, 1.33 g (7.25 mmol) of 3,3,7,7-tetramethylnonane-4,6-dione, and 0.76 g (7.25 mmol) of Na2CO3 were mixed with 40 mL of ethoxyethanol, and then stirred at 90° C. for 24 hours to allow reaction. After the reaction was completed, the temperature was lowered to room temperature to obtain a solid product. This obtained solid product was filtered and then purified by column chromatography to obtain 1.6 g of Compound 1 (Yield: 55%).
