DCzDBT, for blue TADF devices achieving excellent EQE
HBL material to significantly improve device operational lifetimes
DCzDBT, also referred to as mCBT, is a carbazole-based bipolar host material containing two carbazole and one dibenzothiophene units for blue thermally activated delayed fluorescent (TADF) devices achieving excellent external quantum efficiencies (EQE).
With a wide bandgap, DCzDBT has also been used as hole blocking layer (HBL) material to replace BAlq to significantly improve device operational lifetimes.
