摘 要:以对氨基苯甲酸甲酯为起始原料,通过酰肼化、水杨醛缩合,对二甲氨基苯甲醛缩合,经3步合成得到一种席夫碱荧光材料PZ1,其结构经IR、1H NMR、13C NMR、MS表征确证,采用UV-Vis、FS分析了PZ1的光学性质,进行了该材料的细胞毒性评价。结果显示,PZ1呈现特征光学吸收,UV-vis光谱的最大吸收峰处于282 nm,斯托克位移为70 nm,pH=6~9时PZ1荧光性能稳定,此外,经ECV304细胞24 h增殖抑制实验证明,PZ1细胞毒性较小,在医学、生物学领域具有应用前景。

Abstract:Using p-aminobenzoic acid methyl ester, hydrazine hydrate, salicylaldehyde and p-dimethylaminobenzaldehyde as the starting materials, a Schiff base fluorescent material PZ1 was obtained through a three-step process. The material’s structure was characterized by IR, 1H NMR, 13C NMR and MS; optical properties were analyzed using UV-Vis and FS; and the cytotoxicity was evaluated through the inhibition experiment on ECV304 at 24 h. It was indicated that the fluorescent material demonstrated specific optical signals and steady fluorescence versus pH changes, showing a maximal absorbance peak at 282 nm in UV-vis spectrum and a Stokes shift of 70 nm in FS. Moreover, the synthesized material showed low cytotoxicity even when incubated with ECV304 cells for 24 h, which were all in good accordance with the molecular structure design and synthetic design.
