Novel organic electroluminescent compounds and organic electroluminescent device using the same

摘要

Provided are a novel organic electroluminescent compound and an organic electroluminescent device using the same as an electroluminescent material. The disclosed organic electroluminescent compound is represented by Chemical Formula 1:
wherein
Ar 1 represents (C6-C60)arylene, (C3-C60)heteroarylene containing one or more heteroatom(s) selected from N, O and S, 5- or 6-membered heterocycloalkylene containing one or more heteroatom(s) selected from N, O and S, (C3-C60)cycloalkylene, adamantylene, (C7-C60)bicycloalkylene, (C2-C60)alkenylene, (C2-C60)alkynylene, (C1-C60)alkylenethio, (C1-C60)alkyleneoxy, (C6-C60)aryleneoxy, (C6-C60)arylenethio or
and
ring A and ring B independently represent a 5- to 7-membered heterocyclic amino group or a ring selected from the following structures:
wherein
the 5- to 7-membered heterocyclic amino group may further contain NR 21 or one or more heteroatom(s) selected from O and S.
