Title:
NOVEL ACRIDINE DERIVATIVE, AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/230854
Kind Code:
A1
Abstract:
The present invention relates to a novel acridine derivative, and an organic electroluminescent device comprising same. The acridine derivative of the present invention has an intramolecular electron donor and electron receptor, and has excellent thermal stability, and thus an organic electroluminescent device employing the acridine derivative has excellent luminous efficiency and color purity.
