2-Bromodibenzothiophene (CAS number 22439-61-8), mono-brominated dibenzothiophene at 2-postion, is commonly used as an intermediate for the further synthesis of more complex structures as organic semiconductors in light-emitting diodes, field-effect transistors and photovoltaic devices.
Bipolar 4,4′-bis(dibenzothiophene-S,S-dioxide-2-yl)triphenylamine (DSTPA), containing a strongly electron-withdrawing core and a strongly electron-donating core with a biphenyl bridge, has suitable HOMO and LUMO levels for easily accepting both holes and electrons. Having a high fluorescence quantum yield of 0.98 and a high triplet energy level of 2.39 eV, DSTPA can be used as green fluorescent emitter or host material for red phosphors [1].
9-(dibenzothiophen-2-yl)-3,6-bis(carbazol-9-yl)-9H-carbazole (DB2tCz), a host material synthesized from 2-bromodibenzothiophene and 3,6-bis(carbazol-9-yl)-9H-carbazole showed high glass transition temperature (Tg = 185 °C) and triplet energy level (ET = 2.93 eV). Vacuum deposited blue PhOLED device with FIrPic as the phosphorescence emitter and DB2tCz exhibited maximum current efficiency of 35.6 cd A−1, power efficiencies of 29.4 lm W−1, and external quantum efficiencies of 20.0% [2]
