Title:
ORGANIC ELECTROLUMINESCENT MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/197730
Kind Code:
A1
Abstract:
The present invention relates to an organic electroluminescent material, which has a structure as represented by formula (I). Compounds as represented by formula (I) have highly stable electron acceptor groups and electron donor groups, stable chemical bonds are provided among the compounds, and no strong conjugate is present. These characteristics provide the compounds as represented by formula (I) with increased fluorescent quantum efficiency and great electric charge transfer capabilities and to be close to the international standard dark blue, thus facilitating implementation of displays having high color purity.
