Title:
ORGANIC MIXTURE AND USE THEREOF IN ORGANIC ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/120099
Kind Code:
A1
Abstract:
The present invention relates to an organic mixture and the use thereof in an organic electronic device. The organic mixture comprises organic materials H1 and H2, wherein H1 is a compound as shown in the following general formula (1), and the S1(H2)-T1(H2) of H2 is ≤ 0.3 eV, in which S1(H2) and T1(H2) are respectively the singlet energy level and triplet energy level of H2. The mixture comprising organic materials H1 and H2 according to the present invention is applicable to organic electronic devices as a host material. Taking an electroluminescent device for example, same can provide a higher luminous efficiency and device lifetime.
