And the patent contained the following:
An easy metal complex having deep red electroluminescence, high luminous efficiency, good thermal stability of the material, and very wide market prospect is provided. The metal complex with mol. formula is M(LA)X(LB)Y(LC)Z, which was characterized by the following chem. structural formula LAI, LAII and LAIII. The metal complex was used in an organic electroluminescent device, the organic electroluminescent device includes a substrate, an anode layer disposed on the substrate, a hole transport layer disposed on the anode layer, an organic light emitting layer disposed on the hole transport layer, an electron transport layer disposed on the organic light emitting layer, and a cathode layer disposed on the electron transport layer, wherein the material of the organic light emitting layer includes the metal complex. The experimental process involved the reaction of 2-Nitro-1H-benzo[d]imidazole(cas: 5709-67-1).Category: imidazoles-derivatives
