摘要
以对氨基苯甲酸甲酯、水合肼、2,3,4-二羟基苯甲醛、对硝基苯甲醛为起始原料,合成得到一种席夫碱荧光材料,通过IR、^(1)H NMR、^(13)C NMR、MS表征材料结构,采用UV-Vis、FS分析其光学性质。结果显示,苯环与席夫碱C=N键的共轭结构构筑,使得该荧光材料呈现特征光学吸收,UV-Vis最大吸收处于269 nm,斯托克位移为73 nm,此外,该材料表现低毒性,对体外环境EVC304细胞未显示显著抑制作用,具有一定应用前景。
With p-aminobenzoic acid methyl ester,hydrazine hydrate,2,3,4-trihydroxy benzaldehyde and p-nitrobenzaldehyde as the initial materials,a Schiff base fluorescent material was synthesized.The material's structure was characterized by IR,^(1)H NMR,^(13)C NMR and MS,its optical properties were analyzed using UV-Vis and FS.It was indicated that the synthesized fluorescent material,with conjugated benzene and Schiff carbon-nitrogen double bond,showed specific optical absorbance,steady fluorescence and low cytotoxicity,giving off the maximal absorbance peak located at 269 nm in UV-Vis spectrum and a Stokes shift of 73 nm in FS.Furthermore,the material demonstrated nearly no significant cytotoxic effect on ECV304 cells,which would show a good application prospect.
