摘　　要：荧光传感器由于具有高灵敏度和高选择性,在检测化学方面得到广泛的应用。本文合成了具有活性荧光团的二芳基喹喔啉衍生物(1～4),并对其进行表征。化合物3同时具有聚集诱导发光(AIE)特征的二芳基喹喔啉、和Hg2+具有特殊反应的1,3-二硫杂环戊二烯-2-硫酮基团,我们将这两个特征基团耦合在同一个化合物之中,从而构建了一类新的"开启"型汞离子荧光传感器。Fluorescence sensing is a powerful tool for detection of chemical species due to its high sensitivity and selectivity. New aggregation-induced emission（ AIE）-active fluorophores,diarylquinoxaline derivatives（ 1 ～ 4）,are synthesized and characterized. By the combination of diarylquinoxaline core and a 1,3-dithiole-2-thione unit,compounds 3,4 are used as ＂turn on＂chemosensors for Hg^2＋ by taking use of the AIE feature of diarylquinoxaline core and the specific reaction of 1,3-dithiole-2-thione with Hg^2＋. Compound 3 especially displays a good selectivity towards Hg^2＋ over other common heavy metal ions.
