研究目的
To systematically summarize the recent progress in chiral emitter based OLEDs with CPEL properties, including CPEL based on chiral conjugated polymers, CPEL based on chiral metal complexes, and CPEL based on chiral simple organic molecules, especially chiral thermally activated delayed fluorescence (TADF) molecules.
研究成果
The review concludes that while significant progress has been made in the development of CP-OLEDs, the field is still in its infancy. It emphasizes the need for new chiral emitters with both high PLQYs and large g values, new strategies for constructing CPEL materials, and the exploration of new device structures and technologies to improve device performances. The ultimate goal is the practical application of CP-OLEDs in areas such as 3D displays, optical data storage, and optical spintronics.
研究不足
The review highlights the limitations of current CP-OLED technologies, such as the generally low efficiencies and small gEL values of devices based on chiral metal complexes and the challenge of achieving both high device performances and large gEL values in chiral simple organic molecules.
