Abstract

We synthesized two thermally activated delayed fluorescent (TADF) emitters sensitizers, 9,9′,9″-(5-(4,6-diphenyl-1,3,5-triazin-2-yl)benzene-1,2,3-triyl)tris(3,6-dimethyl-9H-carbazole) (TmCzTrz) and 9,9′,9″-(5-(4,6-diphenyl-1,3,5-triazin-2-yl)benzene-1,2,3-triyl)tris(3,6-di-tert-butyl-9H-carbazole) (TbCzTrz) to investigate as the sensitizers in hyper-fluorescent organic light emitting diodes (OLEDs). The difference in two TADF sensitizers was the side group that was consisted of methyl and t-butyl group. Although the efficiency of TbCzTrz based TADF device was lower than that of the TmCzTrz device, the efficiency of the hyper-fluorescent device using the as sensitizers was almost the same.
