Patent abstract
The invention provides a method for producing an iridium complex with a high yield at a low temperature, and an organic electroluminescence device (organic EL device) having an light output high in efficiency and high luminance in a range from blue to red region. An iridium complex for the organic EL device is produced from an iridium complex having a 4-membered ring structure as an auxiliary ligand. The organic EL device is composed of at least a pair of electrodes serving as an anode and a cathode, and an organic compound layer interposed between the electrodes, and the organic compound layer contains an iridium complex represented by a following structure:
