Used in organic electronics, particularly in the development of hole-transport materials for OLEDs (organic light-emitting diodes). Its rigid carbazole core with methyl substituents enhances thermal stability and improves film-forming properties, making it suitable for use in emissive layers and as a host material in blue phosphorescent OLEDs. Also employed as a building block in synthesizing larger conjugated systems for photovoltaic applications. Its derivatives show promise in perovskite solar cells due to good charge transport characteristics and compatibility with device architectures.
