A multi-function fluorescent probe HT was synthesized from 2,4-dihydroxybenzaldehyde and 6-methoxy-2-naphthaldehyde. HT demonstrated a remarkable turn on response to detect Zn in ethanol solution with strong anti-interference ability. Additionally, HT exhibited exceptional proficiency in discerning minute traces of water present in conventional organic solvents. The detection limit for Zn was 1.88 × 10 mol·L, with a coordination ratio of 2:1 between HT and Zn. Furthermore, the detection limits of HT for water in various solvents such as EtOH, DMSO, DMF, CHCN, THF, 1,4- Dioxane were 0.0089%, 0.0211%, 0.0364%, 0.0472%, 0.0161%, 0.0116% (V/V), respectively. Moreover, HT demonstrated its practical application potential by accurately determining the alcohol content in different Chinese Baijiu samples.
一种多功能荧光探针HT由2,4 - 二羟基苯甲醛和6 - 甲氧基 - 2 - 萘甲醛合成。HT在乙醇溶液中对锌的检测表现出显著的开启响应,具有很强的抗干扰能力。此外,HT在识别传统有机溶剂中微量水分方面表现出卓越的能力。锌的检测限为1.88×10⁻⁶mol·L⁻¹,HT与锌的配位比为2:1。此外,HT对乙醇、二甲基亚砜、二甲基甲酰胺、乙腈、四氢呋喃、1,4 - 二氧六环等各种溶剂中水分的检测限分别为0.0089%、0.0211%、0.0364%、0.0472%、0.0161%、0.0116%(V/V)。此外,HT通过准确测定不同中国白酒样品中的酒精含量展示了其实际应用潜力。
