Red Multi‐Resonant Thermally Activated Delayed Fluorescence Emitters as Bioimaging Agents

open access: yesAdvanced Optical Materials, EarlyView.
Multi‐resonant thermally activated delayed fluorescence (MR‐TADF) emitters have attracted strong interest for use in electroluminescent devices due to their high photoluminescence quantum yield and narrowband emission. These properties, along with red emission, are also crucial for bioimaging probes.
