Abstract

The regulation of switching between thermally activated delayed fluorescence (TADF) and room-temperature phosphorescence (RTP) is meaningful but challenging. This study designs N-phenylacridone derivatives to achieve reversible switching between TADF and RTP afterglow via protonation/deprotonation, enabling applications in anti-counterfeiting and data encryption.
