Acridone-amine D-A-D thermally activated delayed fluorescence emitters with narrow resolved electroluminescence and their electrochromic properties

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 TADF and UV electrochromic properties. Structure-property relationships are studied using electrochemical spectroelectrochemical methods well photophysical characterization. successful emitters used OLED, (FWHM = 66-85 nm) electroluminescence the green region with maximum EQE 5.4%.
