Organic thermally activated delayed fluorescence (TADF) compounds used in photocatalysis

open access: yesChemical Society Reviews, 2021
Organic compounds that show Thermally Activated Delayed Fluorescence (TADF) have become wildly popular as next generation emitters in organic light-emitting diodes (OLEDs), but since 2016, have received significant and increasing attention as photocatalysts.
