Organic electroluminescent compounds and organic electroluminescent device comprising the same

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. 本发明涉及有机电致发光化合物，和主体材料、电子缓冲材料、电子传输材料以及包含其的有机电致发光装置。通过使用本发明的有机电致发光化合物，有机电致发光装置通过分子间堆叠和相互作用确保快速的电子流特性，并且因此可以提供具有低驱动电压和/或极佳的发光效率和/或高效的使用寿命特性的有机电致发光装置。
