Purely Organic Dyes with Thermally Activated Delayed Fluorescence—A Versatile Class of Indicators for Optical Temperature Sensing

Carbazole‐substituted dicyanobenzenes and anthraquinone based intramolecular charge‐transfer dyes, two classes of organic thermally activated delayed fluorescence (TADF) emitters developed for organic light‐emitting diode (OLED) technology, are prepared and investigated for their suitability for optical oxygen and temperature sensing. The new materials do not offer any improvement compared to the state‐of‐the‐art probes in respect to oxygen...
