More Information
Summary:Provided are an organic electroluminescent material and a device thereof. The organic electroluminescent material includes a metal M and at least one C{circumflex over ( )}N bidentate ligand La coordinated with the metal M, the maximum emission wavelength of the photoluminescence spectrum of the organic electroluminescent material at room temperature is greater than or equal to 410 nm and less than or equal to 700 nm, and the emission spectrum area ratio of the organic electroluminescent material is less than or equal to 0.145. The metal complex has significant advantages in organic electroluminescent devices, in particular the improvement of device efficiency. Further provided are an organic electroluminescent device including the metal complex and a compound composition including the metal complex.
