Abstract
. This work is the first instance of developing high-performance ultra-deep-blue solution-processed TSCT-TADF OLEDs, which show comparable performance to vacuum-deposited OLEDs. Furthermore, the 3MeCz-BO-based OLED fits well within the standard Red Green Blue (sRGB) of CIE coordinates (0.15, 0.06), and is close to the CIE coordinates (0.131, 0.046) for the Rec. 2020 standard, implying its potential application in colorful display devices.
