NOVEL CHRYSENE COMPOUND AND ORGANIC LIGHT-EMITTING DEVICE USING SAID COMPOUND Russian patent published in 2013 - IPC C07C15/38 C07C15/20 C09K11/06 H01L27/32 H01L51/50 

FIELD: chemistry.

SUBSTANCE: invention relates to a chrysene compound of general formula [1]: , where each of R₁-R₉ denotes a hydrogen atom, and Ar₁ Ar₂ and Ar₃ are each independently selected from a group represented by general formulae [2]:

where X₁-X₂₆ are each independently selected from a group consisting of a hydrogen atom, an alkyl group consisting of only carbon and hydrogen, containing 1-4 carbon atoms, a phenyl group which can be substituted with an alkyl group consisting of only carbon and hydrogen, containing 1-4 carbon atoms, a naphthyl group which can be substituted with an alkyl group consisting of only carbon and hydrogen, containing 1-4 carbon atoms, a phenanthryl group which can be substituted with an alkyl group consisting of only carbon and hydrogen, containing 1-4 carbon atoms, and a fluorenyl group which can be substituted with an alkyl group consisting of only carbon and hydrogen, containing 1-4 carbon atoms, under the condition that one of X₁-X₈, one of X₉-X₁₆ and one or X₁₇-X₂₆ each independently denotes a chrysene ring represented by general formula [1]; and Y₁ and Y₂ are each independently selected from an alkyl group consisting of only carbon and hydrogen, containing 1-4 carbon atoms. The invention also relates to an organic light-emitting device and a display using said compound.

EFFECT: use of the disclosed compound sufficiently increases emission efficiency and service life.
