New synthesis of highly potential efficient bluish-green electroluminescent materials based on 1,3,4-oxadiazole–triazolopyridinone–carbazole derivatives for single-layer devices

New potential bluish-green electroluminescent materials of 1,3,4-oxadiazole–triazolopyridin- one–carbazole derivatives were synthesized and characterized for single-layer devices. Carbazole, pyridine, and triazolopyridinone were completely introduced into 1,3,4-oxadiazole skeletal to play assistant roles in controlling fundamental photolytic process due to the electron-donating nature, excellent photoconductivity, and flexible structure properties. Following the spectroscopic studies and the measurements of cyclic voltammogram, 1,3,4-oxadiazole–triazolopyridinone–carbazole derivatives were highly efficient bluish-green electroluminescent materials. © 2006 Wiley Periodicals, Inc.
