Synthesis and excited state modulation of organic blue light emitters based on 2,4,6-triphenyl-1,3,5-triazine and carbazole derivatives through ortho-positioned linking models

Abstract

Here, 9-(2-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)-9H-carbazole (OSTrPhCz) is used as a model emitter, and carbazole or 2-bromized carbazole are introduced into the ortho- positions of 2,4,6-triphenyl-1,3,5-triazine framework to generate two emitters, namely OTrPhCz and...

New strategy for developing deep blue TADF materials with narrow emission and CIEy < 0.06 employing host materials as donors

“…In recent years, TADF emitters have become the most promising new luminescent materials, [1][2][3][4][5] which can efficiently convert triplet excitons to singlet excitons through a reverse intersystem crossing (RISC) process, and obtain nearly 100% internal quantum efficiency (IQE). [6][7][8][9][10][11] Especially, narrow-emission TADF emitters have very important applications in ultra-highdefinition display panels.…”
