Abstract:
Provided are novel organic electroluminescent compounds, and organic electroluminescent devices and organic solar cells employing the same. Specifically, the organic electroluminescent compounds according to the invention are characterized in that they are represented by Chemical Formula (1): wherein, A, B, C and D independently represent CR5 or N, provided that A, B, C and D cannot represent CR5 all at the same time. Since the organic electroluminescent compounds according to the invention have good luminous efficiency and excellent color purity and life property of material, OLED's having very good operation life can be manufactured therefrom.
