Solution-processed Organic light-emitting diodes (OLEDs) have aroused serious attention because of its lower cost and easier fabrication. Herein, a novel triazine-based molecular emitter is reported for solution-processed OLEDs for the first time. The emitter, 4,4′,4′'-(1,3,5-triazine-2,4,6-triyl)tris(N,N-bis(4-(3,6-di-tert-butyl-9H-carbazol-9-yl)phenyl)aniline) denoted as Tri-2tCzPA-TRZ, shows excellent solubility in common organic solvents, facilitating solution-processed OLEDs. The resultant OLEDs doped with 1,3-di(9H-carbazol-9-yl)benzene (mCP) achieved a maximum current efficiency of 18.8 cd A
−1 and maximum luminance of 12,580 cd m−2 , which is higher than the maximum current efficiency of the most solution-processed OLEDs in simple structures. [ABSTRACT FROM AUTHOR]- Published
