This chemical is widely used in the field of organic electronics, particularly in the development of organic light-emitting diodes (OLEDs). Its unique structure, combining carbazole and diphenylphosphine groups, makes it an effective host material in phosphorescent OLEDs, enhancing device efficiency and stability. Additionally, it serves as a ligand in transition metal catalysis, facilitating various organic transformations, including cross-coupling reactions. Its phosphine moiety also makes it valuable in coordination chemistry, where it stabilizes metal complexes for use in catalytic processes.
