Title:
CYANO GROUP-SUBSTITUTED HETEROARYL AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/022417
Kind Code:
A1
Abstract:
Provided is a cyano group-substituted heteroaryl amine derivative which effectively absorbs high-energy external light source in the UV region to minimize damage to organic materials inside an organic electroluminescent device, thus contributing to substantial improvement in the lifespan of the organic electroluminescent device. The organic electroluminescent device according to the present invention comprises: a first electrode; a second electrode; at least one organic material layer provided between the first electrode and the second electrode; and a capping layer, wherein the capping layer includes a cyano group-substituted heteroaryl amine derivative represented by chemical formula 1 according to the present invention.
