Abstract:

Due to the rich luminescent properties of organic materials, the application of organic light-emitting diodes (OLEDs) in flat panel displays and lighting has received widespread attention. Traditional organic light-emitting diodes mainly rely on triplet emitters based on organic small molecules or precious metal complexes, such as platinum?(?Ⅱ?) and iridium?(Ⅲ??), which have poor thermal stability, limited carrier transport capacity, difficulty in obtaining, limited performance, and high material prices, seriously limiting their applications and development. Cu?(?Ⅰ) complexes have excellent luminescent properties, tunable emission, and relatively low cost, providing a new approach for developing metal complex luminescent materials. This article summarizes the research progress of electroluminescence based on Cu?(Ⅰ) complexes, explores strategies for adjusting luminescence by changing the types of the coordination atoms and the structures of ligands, and looks forward to the development prospects of electroluminescence in Cu?(Ⅰ?) complex materials.

Key words: Cu(Ⅰ) complexes, Organic light-emitting diodes, Electroluminescence
