Narrowband Emissive Thermally Activated Delayed Fluorescence Materials (Advanced Optical Materials 22/2022)

In article number 2201714, Hyung Jong Kim and Takuma Yasuda review the recent advances in narrowband emissive multiple-resonance thermally activated delayed fluorescence (MR-TADF) materials from the perspective of molecular design, photophysical properties, and electroluminescence performances in organic light-emitting diodes (OLEDs). MR-TADF materials that enable high-efficiency and high-color-purity electroluminescence will make a great contribution as a key technology for ultrawide-color-gamut OLED displays.
