✦ Synopsis

New potential bluish-green electrolumi- nescent materials of 1,3,4-oxadiazole-triazolopyridinone-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-triazolopyridinonecarbazole derivatives were highly efficient bluish-green electroluminescent materials.
