有机电致发光材料噁二唑衍生物的合成

Synthesis of 1,3,4-Oxadiazole Derivatives for Organic Electro-transporting Electroluminesent Materials

由酰氯与各种酰肼反应得到中间体 4,进而用三氯氧磷脱水闭环 ,合成了一系列 1,3 ,4 二唑衍生物 5 ,用1HNMR ,IR ,MS和元素分析对其结构进行了确证 .这类化合物是较有前景的有机电致发光材料 .

1,3,4-Oxadiazole derivatives (5) were prepared from hydrazide (3), which were converted with acylchloride in pyridine into N-substituted hydriazide (4), followed by treatment with phosphorus oxychloride. The newly synthesized compounds were characterized by H-1 NMR, IR, MS and elemental analyses. These compounds represent potential organic electro-transporting electroluminesent (EL) materials.
