Kind Code:
A1
Abstract:
An embodiment of the present invention relates to: a boron compound in which specific nitrogen is substituted with oxygen or sulfur; and an organic light-emitting device including same and, more specifically, to a boron compound and an organic light-emitting device including same, wherein the boron compound can realize a deep-blue wavelength with improved delayed fluorescence properties along with improved narrow full-width at half maximum properties by shifting a short wavelength due to a shortened conjugation length, through a chemical structure in which oxygen or sulfur having greater electronegativity than nitrogen is positioned around boron in a delayed fluorescence structure in a multi-resonant form including diboron.
