Title:
COMPOUND HAVING π-ELECTRON CONJUGATED UNIT AND CARBAZOLE GROUP
Document Type and Number:
WIPO Patent Application WO/2019/087936
Kind Code:
A1
Abstract:
Provided is a novel compound which can increase luminous efficiency when used as a material of a light-emitting layer of an organic light-emitting element or the like, and which also exhibits excellent light stability. This compound is characterized by containing one or more benzene rings, and in that two or more carbazole groups are bonded to a benzene ring in a π-electron conjugated unit (A) that satisfies 1) and/or 2) below, and all of the carbazole groups have a CF3 group at the 3-position and 6-position. 1) A substituent group (E) whose Hammett substituent group constant σpara is positive is bonded to the π-electron conjugated unit (A). 2) The π-electron conjugated unit (A) has an aromatic hydrocarbon ring or an aromatic heterocyclic ring in addition to the benzene ring, and -CO-, -SO2- or -CF2- links to the benzene ring and the aromatic hydrocarbon ring or the aromatic heterocyclic ring.
