Abstract

A five-stage method for the synthesis of Y-shaped push–pull fluorophores based on 2-(4'-methoxyphenyl)-1,2,3-triazole was proposed. The resulting molecules exhibited emission in the range from 350 to 450 nm with high quantum yields (QY) of 90–99% in solvents of various polarity. The products proved to be applicable as chemosensors for both aromatic and aliphatic nitro analytes in concentrations down to 300 ppb.

基于 N(2)-芳基-1,2,3-三唑的 Y 型荧光团：用于检测硝基芳香族化合物的光物理和化学传感器特性的合成与研究

摘要提出了一种五步合成基于 2-(4'-甲氧基苯基)-1,2,3-三唑的 Y 型推挽荧光团的方法。在不同极性的溶剂中，所得分子的发射波长范围为 350-450 nm，量子产率（QY）高达 90-99%。事实证明，这些产品可用作芳香族和脂肪族硝基分析物的化学传感器，其浓度可低至 300 ppb。
