A colorimetric sensor 1,N,N'-di-(2-hydroxy-5-(phenldiazenyl)benzaldehyde)-1,3-diiminothiourea for acetate in DMSO and 9/1 DMSO/H(2)O (v/v) mixtures was designed and synthesized. The binding ability evaluated by UV-vis experiment reveals that sensor 1 can selectively recognize acetate. In addition, the color changes induced by anions can provide a way of detection by 'naked-eye'. The further insights to the nature of interactions between the sensor 1 and AcO(-) were investigated by (1)H NMR titration experiments in 9/1 DMSO-d(6)/H(2)O (v/v).
设计并合成了一种用于 DMSO 和 9/1 DMSO/H2O（v/v）混合物中乙酸的比色传感器 1，N,N'-二-（2-羟基-5-（苯基偶氮基）苯甲醛）-1,3-二亚氨基硫脲。通过紫外可见实验评价的结合能力表明，传感器 1 可以选择性地识别乙酸根。此外，阴离子诱导的颜色变化可以通过“肉眼”提供一种检测方法。通过在 9/1 DMSO-d6/H2O（v/v）中进行1H NMR 滴定实验，进一步研究了传感器 1 与 AcO-之间相互作用的性质。
