A quinoxaline-based, new bipolar organic compound is provided, and a light emitting element using the quinoxaline-based compound is demonstrated. The quinoxaline derivative of the invention has a structure in which carbon at one or both of the 2-position and the 3-position of the quinoxaline unit are bonded, via an arylene group, with an amine unit which has a substituted or unsubstituted five-membered ring or a substituted or unsubstituted condensed ring containing a five-membered ring structure. The quinoxaline-based compound was proven to possess bipolar characteristics in view of carrier transportation, which allows the fabrication of a light emitting element and an electronic appliance with a low driving voltage and low power consumption.
本发明提供了一种基于喹喔啉的新型双极有机化合物,并演示了使用该基于喹喔啉的化合物的发光元件。该发明的喹喔啉衍生物具有结构,在其中,喹喔啉单元的2位和/或3位的碳通过芳基烃基团与一种含有取代或未取代的五元环或含有五元环结构的取代或未取代的缩合环的胺单元键合。基于喹喔啉的化合物被证明具有双极特性,具有载流子传输的特性,这允许制造具有低驱动电压和低功耗的发光元件和电子设备。
