摘要:

由于有机材料丰富的发光特性,有机发光二极管(OLEDs)在平面显示器和照明中的应用获得了广泛的关注。传统的有机发光二极管发光层材料主要为有机小分子或贵金属配合物,其中贵金属配合物,如铂(Ⅱ)和铱(Ⅲ),存在热稳定性较差、载流子传输能力有限、获取难度大、性能受限和材料价格高昂等问题,严重限制了其应用和发展。Cu(Ⅰ)配合物具有优异的发光特性、发射可调性和相对较低的成本,为开发金属配合物发光材料提供了新的途径。本文总结了基于Cu(Ⅰ)配合物的OLEDs发光材料的研究进展,探讨了改变配位原子类型和配体结构调节Cu(Ⅰ)配合物电致发光的策略,对Cu(Ⅰ)配合物OLEDs发光材料的发展前景予以展望。

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
