The present invention discloses a fused pyrrole derivative and application thereof in an organic electronic device, particularly an organic light emitting diode. The fused pyrrole derivative has a characteristic structure represented by general formula (I). The derivative compound exhibits a good rigidity, chemical stability and thermal stability, thereby effectively enhancing a color purity, stability, and luminous efficiency of the compound as well as a performance of the corresponding device. By further optimizing device structure and modifying a concentration of the fused pyrrole derivative in a matrix, optimal device performance can be achieved to create an OLED device with a high efficiency, high brightness and high stability. Thus, the present invention provides a preferred material option for applications in full color display and lighting. |
