High-Efficiency, Long-Lifetime and Color-Tunable Hybrid WOLEDs Using a Platinum Complex with Voltage-Dependent Monomer and Aggregate Emission.

ABSTRACT: Color-tunable white organic light-emitting diodes (CT-WOLEDs) have attracted widespread attention given their large color variation to meet the different daily scenarios from the perspective of circadian rhythm. However, most reported CT-WOLEDs, especially the tri-color devices, exhibit poor performances and sophisticated structures. Here, a simple structure tri-color CT-WOLED is demonstrated that simultaneously exhibits high efficiency, ultralong operation lifetime, and wide color-tunable range for dynamic sunlight emulation. The design is based on a newly developed platinum complex that can emit light efficiently in both monomer and aggregation states, providing voltage-dependent green-to-red phosphorescence emission, not only ensuring tunable colors in WOLEDs but also simplifying the de
