Provided are novel organic electroluminescent compounds characterized in that they are represented by Chemical Formula (1):
wherein, ring A and ring B independently represent a saturated 5- or 6-membered heterocyclic amino group, or a substituent selected from the following structures:
wherein the saturated 5- or 6-membered heterocyclic amino group may further comprise one or more heteroatom(s) selected from NR36, O and S; and
a and b independently represent an integer from 0 to 4, provided that (a + b) is an integer from 1 to 4.
本发明提供了新型有机电致发光化合物,其特征在于它们由
