An organic compound having a tetraphenyl moiety and at least one fused hetero aryl moiety having at least one oxygen and/or sulfur on a ring and bonded to the tetraphenyl moiety directly or indirectly, and a light emitting diode and a light emitting device having the organic compound are disclosed. The organic compound has excellent thermal resistance property and hole mobility property. The organic compound can be incorporated into a hole transfer layer, an electron blocking layer and/or a charge generation layer of the light emitting diode. Therefore, the light emitting diode and light emitting device according to the present invention have decreased driving voltage and enhanced luminous efficiency.
本发明公开了一种具有四苯基基团和至少一个融合的杂环芳基团的有机化合物,该杂环芳基团在环上至少含有一个氧和/或
硫,并直接或间接地与四苯基基团结合,以及具有该有机化合物的发光二极管和发光器件。该有机化合物具有优异的热阻性能和空穴迁移性能。该有机化合物可以被纳入发光二极管的空穴传输层、电子阻挡层和/或电荷生成层中。因此,根据本发明的发光二极管和发光器件具有降低的驱动电压和增强的发光效率。
