Document Type and Number:
WIPO Patent Application WO/2019/235452
Kind Code:
A1
Abstract:
The present invention increases the options for organic device materials such as organic EL element materials by introducing a specific tertiary alkyl group into novel polycyclic aromatic compounds in which a plurality of aromatic rings are linked by boron atoms and oxygen atoms or the like. The present invention also provides an organic EL element that has, for example, excellent luminous efficiency by using a novel cycloalkyl-substituted polycyclic aromatic compound as an organic EL element material.
