Abstract:
The present disclosure relates to organic electroluminescent compounds, and a host material, an electron buffer material, an electron transport material and an organic electroluminescent device comprising the same. By using the organic electroluminescent compounds of the present disclosure, the organic electroluminescent device secures fast electron current properties by intermolecular stacking and interaction, and thus, it is possible to provide the organic electroluminescent device having low driving voltage and/or excellent luminous efficiency and/or efficient lifespan properties.

Claim (Index 10):
The organic electroluminescent device according to  claim 8 , wherein the organic electroluminescent device comprises at least one light-emitting layer disposed between a first electrode and a second electrode, wherein the light-emitting layer comprises a host and a phosphorescent dopant, wherein the host comprises a plurality of host compounds, and wherein at least a first host compound of the plurality of host compounds is the organic electroluminescent compound, and at least a second host compound of the plurality of host compounds is represented by the following formula 5: wherein A 1  and A2, each independently, represent a substituted or unsubstituted (C6-C30)aryl; with the proviso that a substituent for neither A 1  nor A 2  is a nitrogen-containing heteroaryl; L represents a single bond, or a substituted or unsubstituted (C6-C30)arylene; and Y 1  to Y 16 , each independently, represent hydrogen, deuterium, a halogen, a cyano, a substituted or unsubstituted (C1-C30)alkyl, a substituted or unsubstituted (C2-C30)alkenyl, a substituted or unsubstituted (C2-C30)alkynyl, a substituted or unsubstituted (C3-C30)cycloalkyl, a substituted or unsubstituted (C6-C60)aryl, a substituted or unsubstituted (3- to 30-membered) heteroaryl, a substituted or unsubstituted tri(C1-C30)alkylsilyl, a substituted or unsubstituted tri(C6-C30)arylsilyl, a substituted or unsubstituted di(C1-C30)alkyl(C6-C30)arylsilyl, a substituted or unsubstituted (C1-C30)alkyldi(C6-C30)arylsilyl, or a substituted or unsubstituted mono- or di-(C6-C30)arylamino; or may be linked to an adjacent substituent(s) to form a substituted or unsubstituted (C3-C30), mono- or polycyclic, alicyclic or aromatic ring, whose carbon atom(s) may be replaced with at least one heteroatom selected from nitrogen, oxygen, and sulfur.
