Abstract Acridones have found their role in luminescent materials for OLEDs. Most interestingly, showing potential as weak charge transfer thermally activated delayed fluorescence (TADF) emitters, providing narrow photoluminescence. In this work, we present a comprehensive study of donor-acceptor-donor (D-A-D) acridone-amine derivatives showing TADF and UV electrochromic properties. Structure-property relationships are studied using electrochemical and spectroelectrochemical methods as well as using photophysical characterization. Most successful emitters are used as luminescent materials in OLED, showing narrow (FWHM = 66-85 nm) electroluminescence in the green region with maximum EQE = 5.4%.
