摘要: 合成了新的化合物2,5-双[2,2'-双(5-取代苯基)-1,3,4-噁二唑]噻吩(R—OXD)(R=H,CH3O,CH3,F,CN),用1HNMR和元素分析对其进行了表征.同时,采用循环伏安法对其电化学性能进行了测试.结果表明,除了F—OXD外,这一系列化合物的电子亲和势高于常用电子传输材料PBD,说明它们的电子传输材料性能优良.

关键词: 噻吩, 噁二唑衍生物, 电子亲和势

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.

Key words: Thiophene, Oxadiazole derivatives, Electron affinity
