Abstract
Provides a type of gold(III) complex supported by tetradentate ligand having a structure of formula (I). The light-emitting device prepared by using the complex as a light-emitting layer material or dopant in the light-emitting device has a high external quantum efficiency, and a low efficiency roll-off. In addition, the preparation process of the tetradentate ligand provided in the present disclosure is simple and the yield is satisfactory. More importantly, the preparation reaction of the material is controllable and stable, and has a good reproducibility, and is suitable for industrial application.
