Stable Blue Phosphorescent OLEDs Based on a Tetradentate Pt(II) Complex with Extended π-Conjugation

Pan Tong, Feng Zhan, Wenhao Fang, Chengyao Zhang et autres

Achieving simultaneously high efficiency and long operational lifetime in blue organic light-emitting diodes (OLEDs) remains a major challenge. Herein, we report a newly designed blue tetradentate Pt(II) complex, PtTP, featuring a biphenyl substituent on the benzocarbene moiety to extend π-conjugation and steric …

High-Color-Purity Blue OLEDs with a Small Efficiency Roll-Off Enabled by a Cyanoregulated Tetradentate Platinum(II) Complex

Kewei Xu, Feng Zhan, Zhibin Li, Qingshan Chu et autres

Organic light-emitting diodes (OLEDs) have emerged as a pivotal technology for full-color displays, and emitters are critical to their device performances. This work developed a new tetradentate Pt(II) emitter, PtON-CN, through a cyano (CN) group functionalization at the phenyl moiety. The CN …

Platinum(II) Phosphors Featuring 3D Geometry and Locally Excited State for High-Performance Deep-Blue OLEDs

Qingshan Chu, Huanhuan Yao, Kewei Xu, Yuanbin She et autres

Organic light-emitting diodes (OLEDs) have become mainstream display technology, but it is still limited by the low device efficiency of blue OLEDs, and robust emitters are highly needed for developing high-performance deep-blue OLEDs. In this work, we developed a strategy to design …

Chemical Reactions in Organic Light‐Emitting Diodes

Guijie Li, Qingshan Chu

Device lifetime is an important parameter in device performance, especially for the blue organic light-emitting diode (OLED) with relatively poor operational stability. Potential chemical degradation reactions are one of the critical reasons for the short operational lifetimes of OLEDs; some degradation products …
