Title:
COMPOSITION FOR FORMING LUMINESCENT LAYER OF ORGANIC ELECTROLUMINESCENT ELEMENT, ORGANIC ELECTROLUMINESCENT ELEMENT, ORGANIC EL DISPLAY DEVICE, AND ORGANIC EL ILLUMINATION
Document Type and Number:
WIPO Patent Application WO/2022/138790
Kind Code:
A1
Abstract:
A composition for forming a luminescent layer of an organic electroluminescent element that includes a polycyclic heterocyclic compound represented by formula (1), a compound represented by formula (20), and an organic solvent. Provided is an organic electroluminescent element with a long drive life that has a luminescent layer containing a polycyclic heterocyclic compound that contains boron. (Ring a, ring b, and ring c are aromatic hydrocarbon rings or aromatic heterocycles. Y is O, N-R, or S. R is an aromatic hydrocarbon ring group, aromatic heterocyclic group, or an alkyl group. R may bond with a carbon atom adjacent to an atom bonded to Y in at least one of rings a-c by -O-, -S-, -C(-Ra)2-, or a single bond. Ra is a hydrogen atom or an alkyl group.) (Ar21-Ar35 are a hydrogen atom or a structure in which one or 2-10 benzene ring structures are unbranched or branched and linked.)
