are as defined in the specification. The carbazole-based compound has good electrical characteristics and charge transport capability, and thus, is useful as a hole injection material, a hole transport material, and/or an emitting material for fluorescent or phosphorescent devices capable of producing light of a full spectrum of colors, including red, green, blue, and white, thereby making it possible to produce an organic light-emitting device with high efficiency, a low driving voltage, and high brightness.
提供了一个以下式代表的基于咔唑的化合物和包括该基于咔唑的化合物的有机发光器件:其中R1、R2、R3、R4、R5、R6、R7、R8、R9、R10、R11、R12、R13和R14如规范中所定义。该基于咔唑的化合物具有良好的电学特性和电荷传输能力,因此,可用作全光谱颜色(包括红色、绿色、蓝色和白色)的荧光或磷光器件的孔注入材料、孔传输材料和/或发射材料,从而使得能够生产具有高效率、低驱动电压和高亮度的有机发光器件成为可能。
