PRODUCTION METHOD FOR AN INTERMEDIATE FOR A BLUE-LIGHT-EMITTING SUBSTANCE USING ANTHRONE

摘要

The present invention relates to a production method for an intermediate for a blue-light-emitting substance using anthrone. A characterising feature of the method of the present invention is that an intermediate for a blue-light-emitting substance is produced using anthrone at a temperature of between -40 and 20°C in an ethyl ether solvent. When this method is employed, the target intermediate for a blue-light-emitting substance, which is used in an organic light-emitting element, can be produced in high yield and in a way that is both economical and straightforward, while also being fixed, by compensating for the shortcomings of Suzuki coupling of the prior art.
