Title:
THERMAL EXCITATION DELAY FLUORESCENT MATERIALS, POLYMER, MIXTURE, COMPOSITION, AND ORGANIC ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/092495
Kind Code:
A1
Abstract:
Disclosed is a thermal excitation delay fluorescent material capable of improving luminous efficiency and stability, a polymer, a mixture, a composition, and an organic electronic device comprising same.This thermal excitation delay fluorescent material comprises a conjugated unit comprising at least two aromatic rings or heteroaromatic rings, so as to achieve thermal excitation delay fluorescence (TADF) luminescent characteristics. This thermal excitation delay fluorescent material can be used as a TADF luminescent material to improve the luminous efficiency and stability of the electroluminescent device containing such a thermal excitation delay fluorescent material by cooperating with a suitable host material, thereby providing a solution of the luminescent device which has low manufacturing cost, a high efficiency, a long life, and being low in roll-off.
