Research on 1,2-Bis(2'-(5'-Phenyloxadiazol-1',3',4'-yl)) Ethylene and Its Derivatives with Substi-tuents on 5'-Phenyl Groups

合成了反式-1,2-双[2′-(5′-苯基(口恶)二唑-1′,3′,4′-基)]乙烯及其二十种5′-取代苯基的衍生物,测定了它们的熔点、红外光谱、紫外光谱、荧光谱光及激光转换效率,并用相对法测定了它们的荧光量子产率。

By dehydration of fumaric dihydrazide and benzoic acid as well as substituted benzoic acids respectively, in polyphosphoric acid, trans-l,2-bis ( 2/-(5/-phenyl-oxadiazol-1',3/,4/-yl))ethylene and twenty of its derivatives with substituents on 5'-phenyl groups were synthesized, of which, the melting points, infrared spectra, ultraviolet spectra, fluorescence emission spectra, laser conversion efficiencies were determined. Their fluorescence quantum yields were obtained by the relative method as well.
