Abstract

Preparation of n{circumflex over ( )}n{circumflex over ( )}c{circumflex over ( )}n tetradentate platinum (ii) complex and uses thereof are provided. The complex of the present invention has a structure as shown in Formula (11). The performance of an organic electroluminescence device prepared from the complex of the present invention is better than that of a reference device. A great application value is realized on an OLED (organic light-emitting diode), and the N{circumflex over ( )}N{circumflex over ( )}C{circumflex over ( )}N tetradentate platinum (II) complex can be used as a phosphorescent doped material to manufacture an orange red light OLED device with a high luminous efficiency.
