Popis: | This work rationalizes, for the first time, the electroluminescent behavior of a representative red-emitting contorted nanographene – i.e., hexabenzoovalene derivative – in small molecule light-emitting electrochemical cells (SM-LECs). This new emitter provides devices with irradiances of ca. 220 μW cm−2 (242 cd m−2), external quantum efficiencies (EQE) of 0.78% ( |
