Abstract
A binuclear organometallic complex enabling highly efficient phospholuminescence and an organic electroluminescent device using the same. The binuclear organometallic complex, which can be suitably used to form an organic layer of an organic electroluminescent device, produces luminescence in the wavelength range of 430-650 nm, and induces white electroluminescence when combined with green and red luminescent materials.
