Abstract
Provided are an organic electroluminescence device which: can emit blue light having a short wavelength and a high color purity; and can be combined with any other light emitting compound to emit white light and a metal complex compound for realizing the device, and a material for an organic electroluminescence device. The metal complex is of a specific structure having a tridentate chelate ligand and an electron withdrawing group. The material for an organic electroluminescence device is formed of the metal complex compound. The organic electroluminescence device has an organic thin film layer formed of one or more layers including at least a light emitting layer, the organic thin film layer being interposed between a pair of electrodes. In the organic electroluminescence device, at least one layer of the organic thin film layer contains the metal complex compound, and emits light by applying a voltage between both the electrodes.
