Organic TADF materials design
This themed issue covers organic thermally activated materials design. The corresponding compounds can be used as components in organic light-emitting diodes (OLEDs), as photocatalysts, as imaging or sensing reagents, or as lasing materials. The focus herein is on the design, synthesis, properties, and use of thermally activated delayed fluorescence (TADF) compounds.
