Application

3,9′-Bicarbazole is widely used as a key intermediate in the development of organic light-emitting diodes (OLEDs) due to its high hole mobility and thermal stability. Its bifunctional carbazole structure enables efficient host materials for phosphorescent and thermally activated delayed fluorescence (TADF) emitters. The compound also serves as a precursor for conductive polymers in flexible electronics and as a scaffold for photovoltaic materials in dye-sensitized solar cells (DSSCs). Researchers leverage its planar geometry to design advanced molecular architectures for optoelectronic device optimization.
