Abstract: A series of novel oxadiazole derivatives containing π-excessive five-memberd ring heterocycle-thiophene(R—OXD) have been prepared as the electron transport layer in organic electroluminescent (OEL) devices. Their molecule structures were characterized by 1H NMR and elemental analysis. The results of cyclic voltammetry measurements imply that all these R—OXD but F OXD have a higher electron affinity( EA) than 2-(4-biphenyl)-5-(t-butylphenyl) 1,3,4 oxadiazole(PBD) which implies that they are better electron acceptors than PBD. So they are potentially better materials as the electron transfer.
