TADF‐Type Organic Afterglow

Angewandte Chemie International Edition, 2021
AbstractWe report a highly efficient dopant‐matrix afterglow system enabled by TADF mechanism to realize afterglow quantum yields of 60–70 %, which features a moderate rate constant for reverse intersystem crossing (kRISC) to simultaneously improve afterglow quantum yields and maintain afterglow emission lifetime.

Ultrapure Blue Thermally Activated Delayed Fluorescence (TADF) Emitters Based on Rigid Sulfur/Oxygen-Bridged Triarylboron Acceptor: MR TADF and D–A TADF

The Journal of Physical Chemistry Letters, 2022
Organic light-emitting diodes (OLEDs) still face a significant challenge in finding blue thermally activated delayed fluorescence (TADF) emitters that can achieve narrowband emission and high efficiency. In this work, we successfully design and synthesize a novel kind of TADF emitters based on rigid sulfur/oxygen-bridged triarylboron acceptor for ...

TADF and Hyperfluorescence

2021
TADF (Thermally Activated Delayed Fluorescence) is recognized as the third generation of OLED-emitting technology, which provides highly efficient emission without using any rare metals, such as iridium. Fundamental molecule design strategies of TADF were based on the introduction of electron donor and acceptor units in which the π-conjugation was ...

Chemical Tailoring Assisted non‐TADF to TADF Switching in Carbazole‐Benzophenone Emitter – An In‐silico Investigation

ChemPhysChem, 2023
AbstractOrganic light‐emitting diodes (OLEDs) have become one of the most popular lighting technologies since they offer several advantages over conventional devices. In carbazole‐benzophenone (CzBP) OLED devices, the polymeric form of the compound is previously reported to be Thermally Activated Delayed Fluorescence (TADF)‐active (ΔEST ≈0.12 eV ...
