Abstract

Dicyanophenyl derivatives, DCN1-3, were rationally synthesized and their thermally activated delayed fluorescence properties were investigated. OLED devices were further fabricated using DCN1-3. Particularly DCN3 (5-{3,6-di(9H-carbazole-9-yl)-9H-carbazol-9-yl}isophthalonitrile) showed excellent device performances employing TADF mechanism with power efficiency of 15.26Cd/A, luminous efficiency of 8.14 lm/W, the maximum external quantum efficiency of 13.33%, and brightness of 1526 Cd/m<sup>2</sup>.
