An asymmetric hydrazide, (12E, 13E)-2-((naphthalen-1-yl) methylene)-1-(1-(2-hydroxynaphthalen-6-yl) ethylidene) hydrazine (abbreviated as AH) is synthesized and characterized by standard techniques and crystal structure of AH has been obtained. The naked eye detection of F in aqueous acetonitrile (acetonitrile: water=7:3/v:v) by AH has been investigated by UV-Visible titration and in presence of other anions, the limit of detection being 1.31×10(M). The mechanism of F sensing has been explored by H NMR titration. AH undergoes hydrogen bonding with F followed by deprotonation. The practical utility of AH has been explored by successful test kit response and color change in toothpaste solution.
一种不对称的酰肼，（12E，13E）-2-（（萘-1-基）亚甲基）-1-（1-（2-羟基萘-6-基）亚乙基）肼（缩写为 AH）是通过标准技术合成并表征的，并且已经获得了 AH 的晶体结构。通过紫外可见滴定法研究了 AH 在水-乙腈（乙腈：水=7：3/v：v）中的裸眼检测 F 的情况，在存在其他阴离子的情况下，检测限为 1.31×10（M）。通过 1H NMR 滴定法探索了 F 传感的机制。AH 与 F 发生氢键相互作用，然后去质子化。通过成功的试剂盒反应和牙膏溶液中的颜色变化，探索了 AH 的实际用途。
