Editorial: Recent Advances in Thermally Activated Delayed Fluorescence Materials
Chihaya Adachi, Guohua Xie, Sebastian Reineke, Eli Zysman‐Colman
Abstract
Thermally activated delayed fluorescence (TADF) materials design has rapidly evolved over the past eight years since Adachi and co-workers demonstrated that organic donor-acceptor compounds could recruit both singlet and triplet excitons in electroluminescent devices, reaching nearly 100% internal quantum efficiency (Nature, 2012, 492, 234-238). Accompanying new and improved TADF materials has been the enhanced performance of the organic light-emitting diodes (OLEDs), underpinned by a refined understanding of the TADF mechanism and the design rules that govern materials design.This themed issue of Frontiers in Chemistry documents recent advances in TADF materials. The articles in this themed issue provide insight into how TADF materials design has evolved and how the use of TADF materials has expanded beyond OLEDs to sensing, imaging and beyond. Despite the intense focus over the past eight year, this collection clearly demonstrates that there is still much to learn and much from which to be inspired.
