- Synthesis and characterization of polyaromatic compounds using tri(naphthyl)indium
-
(Chemical Equation Presented) A variety of polyaromatic compounds bearing 1- and 2-naphthyl groups were prepared from the reactions of corresponding halides with tri(1- and 2-naphthyl)indium in good to excellent yields. Thermal, photophysical and electrochemical behaviors of carbazoles having naphthyl groups were studied. They have shown to be promising host and hole transporting materials in organic electroluminescence due to their high thermal stability, electrochemical reversibility and wide band gap.
