摘　　要：制备了间氨基苯甲酸缩3,5-二氯水杨醛希夫碱,利用红外(IR)、核磁(1H NMR)、质谱(MS)和元素分析对化合物结构进行了表征。研究了它的荧光性质和热稳定性。对化合物的紫外可见(UV-Vis)光谱和荧光光谱的研究表明,该化合物在DMF溶液中具有较好的光致变色和热致变色性能。化合物的吸光度值和最大发射波长与时间或温度呈线性关系,进一步说明该化合物是性能良好的光致变色及热致变色材料。The title compound,3-（3,5-dichlorobenzylideneamino）benzoic acid was obtained by the condensation of 3-aminobenzoic acid and 3,5-dichlorosalicylaldehyde,and the structure of it was determined by 1H NMR,IR,and high-resolution mass spectra.We have studied its fluorescence performance and thermal stability.The UV and fluorescence spectrums reveal that the title compound possesses favorable properties of photochromism and thermochromism in DMF solution.The analysis also shows that there is a linear relationship between its absorbance and time or temperature,which further demonstrate its photo-and thermochromic properties.
