N-acetylglyoxylic amides 4 and 5 bearing pendant 4-nitrophenyl and 2,4-dinitrophenyl groups respectively were synthesized and evaluated as anion sensors. A crystal structure of 4 was obtained by X-ray crystallography. Compounds 4 and 5 behaved as colorimetric sensors for CN(-) and F(-), and exhibited naked eye-detectable color changes upon the addition of these anions. The chromogenic properties of 4 and 5 were assessed by UV-Vis and (1)H NMR spectroscopy.
分别带有 4-硝基苯基和 2,4-二硝基苯基侧基的 N-乙酰基甘氨酸酰胺 4 和 5 被合成并作为阴离子传感器进行了评价。通过 X 射线晶体学获得了 4 的晶体结构。化合物 4 和 5 对 CN(-)和 F(-)表现出比色传感器的行为，并在加入这些阴离子时表现出肉眼可检测的颜色变化。通过紫外可见光谱和 (1)H NMR 光谱评估了 4 和 5 的显色性质。
