Quinoxaline Derivative, and Light Emitting Element, Light Emitting Device and Electronic Appliance Using the Same |
摘要 |
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.
