High-Efficiency WOLEDs with High Color-Rendering Index based on a Chromaticity-Adjustable Yellow Thermally Activated Delayed Fluorescence Emitter

A chromaticity‐adjustable yellow thermally activated delayed fluorescence (TADF) material, PXZDSO2 as a triplet harvester provides a rational device concept, giving two‐color and three‐color pure organic white organic light‐emitting diodes (WOLEDs) with unprecedented color‐rendering index of 95 and...
