-
Paragraph 0361; 0370-0373; 0506; 0511-0514, (2021/02/02)
The present invention relates to a boron compound usable in an organic light-emitting device, and an organic light-emitting device comprising the same and, more particularly, to a boron compound represented by any one of chemical formula A to chemical formula D and an organic light-emitting device comprising the same. The chemical formula A to chemical formula D are the same as described in the detailed description of the invention. When the novel boron compound is used as a dopant material in an organic light-emitting device, the organic light-emitting device exhibits longer life characteristics compared to the prior art.

Palladium-catalyzed synthesis of pure, regiodefined polymeric triarylamines
Goodson, Felix E.,Hauck, Sheila I.,Hartwig, John F.
, p. 7527 - 7539 (2007/10/03)
Triarylamine polymers were prepared by palladium-catalyzed amination of aryl halides, and the electrochemical and magnetic properties of these materials were studied. Through a careful evaluation of the catalytic and polymer chemistry involved in this pro
