Abstract
The present invention relates to preparation and application of a N{circumflex over ( )}N{circumflex over ( )}C{circumflex over ( )}O tetradentate platinum (II) complex, and belongs to the field of an OLED organic electroluminescence material. The complex of the present invention has the following structural formula, is used for a phosphorescent doped material achieving a photon emission effect in a light-emitting layer of an OLED luminescent device. The complex of the present invention has the advantages of high fluorescence quantum efficiency, high thermal stability and low quenching constant, and can be used for manufacturing an orange red light OLED device with a high luminous efficiency and a low roll-off factor.
