A new and simple phenylhydrazone-based sensor 1 for acetate has been investigated in DMSO and even in the 95:5 DMSO/H2O (v/v) mixtures. Binding of anions such as AcO-, F- and H2PO4(-) results in a noteworthy change in the visible region of spectrum (approximately 100 nm red shift), which can be detected by the 'naked-eye'. The further insights to the nature of interactions between the sensor 1 and AcO- were investigated by 1H NMR titration experiments in DMSO-d(6). In particular, analytical application and detection of acetate ion have been also studied in the aqueous.
一种新型且简单的基于苯腙的醋酸盐传感器1已在二甲基亚砜（DMSO）甚至95:5的DMSO/水（体积比）混合溶剂中进行了研究。醋酸根离子（AcO-）、氟离子（F-）和磷酸二氢根离子（H2PO4(-)）等阴离子的结合会导致光谱可见区域发生显著变化（约100纳米的红移），这可以通过肉眼检测到。通过在氘代二甲基亚砜（DMSO-d(6)）中进行的1H NMR滴定实验，进一步深入研究了传感器1与AcO-之间相互作用的性质。特别是，还研究了该传感器在水溶液中对醋酸根离子的分析应用和检测。
