Document Type and Number:
WIPO Patent Application WO/2016/181844
Kind Code:
A1
Abstract:
In order to provide a π-conjugated compound that increases light-emission efficiency, this π-conjugated compound has: an absolute value for the difference between the lowest excited singlet energy level and the lowest excited triplet energy level that is no more than 0.50 eV; a HOMO energy level for the π-conjugated compound of at least -5.5 eV; and a LUMO energy level of at least -1.8 eV.
