Abstract
Silyl-substituted cyclometalated transition metal complexes have good thermal stability and enabling highly efficient phospholuminescence and an organic electroluminescent device may use the Silyl-substituted cyclometalated transition metal complexes. The transition metal complexes, which are suitably used for forming an organic layer of the organic electroluminescent device, can emit light in the wavelength range of 400-650 nm, and induce white electroluminescence when combined with green or red luminescent materials.
