Thermally Activated Delayed Fluorescence from Pentacarbazorylbenzonitrile

Thermally Activated Delayed Fluorescence from Pentacarbazorylbenzonitrile

A benzonitrile derivative substituted by five carbazoles (5CzBN), which emits thermally activated delayed fluorescence (TADF), was synthesized and evaluated. The organic light-emitting diode (OLED) containing 5CzBN demonstrated light-blue electroluminescence and a high external quantum efficiency of...

Zusammenfassung:A benzonitrile derivative substituted by five carbazoles (5CzBN), which emits thermally activated delayed fluorescence (TADF), was synthesized and evaluated. The organic light-emitting diode (OLED) containing 5CzBN demonstrated light-blue electroluminescence and a high external quantum efficiency of 14.8%.
