Abstract

Abstract : We report a new emitter 3, 4, 5-3TCz-TTT based on a tris(triazolo)triazine acceptor that shows thermally activated delayed fluorescence and cross-compare its performance with the recently reported analogue, 3DMAC-TTT . Abstract : We report a new emitter 3, 4, 5-3TCz-TTT based on a tris(triazolo)triazine acceptor that shows thermally activated delayed fluorescence and cross-compare its performance with the recently reported analogue, 3DMAC-TTT . These compounds show blue emission and delayed fluorescence with delayed lifetimes on the order of milliseconds. Solution-processed organic light-emitting diodes achieving maximum external quantum efficiencies, EQEmax, of 5.8% for 3, 4, 5-3TCz-TTT and 11.0% for 3DMAC-TTT .
