Abstract
Disclosed are new organometallic complex molecules having light-emitting and electron-transporting characteristics. Also disclosed is organic EL (electroluminescent) devices using these organometallic complex molecules as electron-transporting materials. The organometallic complex molecules are used to form a light-emitting layer with or without doping of another light-emitting material. The organometallic complex molecules can also be used in an electron-transporting layer of the organic EL device. The organic EL devices incorporating the organometallic complex molecules have high thermal stability.
