Abstract
New triazolo-carbazole derivatives were synthesized by copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions. The chemical structures of these compounds were confirmed by NMR and FT-IR spectroscopic analysis. The optical properties of the triazolo-carbazoles were investigated by UV-visible absorption and photoluminescence spectroscopy; an emission in the ultraviolet region was observed. The energy levels of these organic materials were determined by cyclic voltammetry and showed a relatively high electronic affinity indicating that they might be good candidates for electron-injection hole-blocking layers in organic light-emitting diodes.
