Abstract

1,3,4-Oxadiazoles carrying triazolopyridinone and carbazolewere synthesized and characterized for the electroluminescent materials in single layer devices. Carbazole and triazolopyridinone were introduced into 2,5-centers of 1,3,4-oxadiazole core to assist the control of fundamental photolytic process due to their electron-donating nature, excellent photo-conductivity, and flexible structure properties. Study from spectrometry and cyclic voltammetry revealed that the 1,3,4-oxadiazole derivatives carrying these two heterocyles are able to be used as the potential bluish-green electroluminescent materials.
