Yellow light emitting compound, manufacturing method thereof, yellow light emitting device and white light emitting device

摘要

The object of the present invention is to provide a yellow luminescent compound which is a novel substance capable of emitting yellow light even though it is a single compound, a production method capable of easily producing such a novel yellow luminescent compound, and the single yellow compound. A yellow light emitting device containing a light emitting compound and a white light emitting device capable of emitting white light by combining the yellow light emitting compound and a blue light emitting compound. The present invention is a yellow light emitting compound represented by the following formula (1), a method for producing the same, and a light emitting device having the yellow light emitting compound. (However, Ar in the formula (1) is a substituent represented by any of the formulas (2), (4) and (5), and the two Ars may be the same or different. R1 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and two R1 may be the same or different.R1a represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms. The two R1a may be the same or different.
