Abstract
Provided are binuclear organometallic complexes enabling highly efficient phospholuminescence and an organic electroluminescent device using the same. The binuclear organometallic complexes, which are suitably used for forming an organic layer of the organic electroluminescent device, provides maximum luminescence emission in the wavelength range of 400-650 nm, and induces white electroluminescence when combined with green or red luminescent materials.
