Abstract

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 external quantum efficiency of 19.2%.

Keywords: chromaticity adjustable; color-rendering index; pure organic; thermally activated delayed fluorescence; white organic light-emitting diodes.
