摘　　要：以间苯二甲酸和2,6-吡啶二甲酸为原料,经酯化、氨解、关环和取代4步反应合成了1,3-二(2-乙酸甲酯基硫醚-1,3,4-噁二唑)-苯和2,6-二(2-乙酸甲酯基硫醚-1,3,4-噁二唑)-吡啶,利用IR、1HNMR及MS对其结构进行表征。在304nm波长光激发下,1,3-二(2-乙酸甲酯基硫醚-1,3,4-噁二唑)-苯(1.0×10-5mol/L的DMF溶液)在357 nm发射荧光;在281 nm波长光激发下,2,6-二(2-乙酸甲酯基硫醚-1,3,4-噁二唑)-吡啶(1.0×10-5mol/L的DMF溶液)在354 nm发射荧光。结果表明,两种目标化合物均具有良好的荧光性能。Two novel compounds 1,3-bis(2-methyl acetate sulfide-1,3,4-oxadiazole)-benzene,and 2,6-bis-(2-methyl acetate sulfide-1,3,4-oxadiazole sulfide-1,3,4-oxadiazole) pyridine were synthesized by esterification,hydrazidation,cyclization and substitution with 1,3-benzenedicarboxylic acid and pyridine-2,6-dicarboxylic acid as starting materials.The structures were confirmed by IR,1HNMR and MS.The fluorescence spectra of the target compounds indicated that the two compounds have good fluorescence with strong flourescence intensity.With the ultraviolet excitement at 304 nm and 281 nm compound 1,3-bis(2-methyl acetate sulfide-1,3,4oxadiazole)-benzene and 2,6-bis-(2-methyl acetate sulfide1,3,4-oxadiazole sulfide-1,3,4-oxadiazole)-pyridine(1.0 × 10-5 mol / L DMF solution) emit fluorescence at 357 nm and 354 nm respectively.
