Abstract
An organometallic complex that increases an energy band gap between HOMO and triplet MLCT states, and enables highly efficient phospholuminescence and can be used for an organic electroluminescent device. The organometallic complex, which is suitably used for forming an organic layer of the organic electroluminescent device, provides a luminescence maximum emission in the wavelength range of 400-650 nm, and induces white electroluminescence when combined with green or red luminescent materials.
