Organometallic compound and organic light-emitting device including the same
摘要
說明書
Hereinafter, compounds and organic light-emitting devices according to embodiments will now be described in detail with reference to synthesis examples and examples. However, these examples are only for illustrative purposes and are not intended to limit the scope of the one or more embodiments of the present disclosure. The wording “B was used instead of A” used in describing synthesis examples means that the amount of A used was identical to the amount of B used, in terms of a molar equivalent.
5 g (29.1 mmol) of 3-bromo-4-methylpyridine was mixed with 60 mL of acetonitrile and 15 mL of water, and then 1.43 g (2.04 mmol) of PdCl2(PPh3)2, 5.5 g (29.1 mmol) of (2-formyl-3-isopropylphenyl)boronic acid, and 10.04 g (72.8 mmol) of K2CO3 were added thereto and heated under reflux at 80° C. for 18 hours. After the reaction was completed, the reaction mixture was concentrated under reduced pressure and then extracted with dichloromethane and water to obtain an organic phase. The obtained organic phase was dried with magnesium sulfate, distilled under reduced pressure, and then purified by column chromatography to obtain 5.71 g of Intermediate L1-4 (Yield: 82%).
