摘　　要：化学传感器提供了方便、快捷、廉价的分析检测有毒重金属离子的方法,具有很高的灵敏度和选择性。检测对象专一的反应型光化学传感器受到越来越多的关注。本文综述了识别Hg2+的反应型光化学传感器的最新研究进展。按照化学反应类型来分类,包括汞促进脱硫和脱硫醇反应、汞促进硫脲衍生物脱硫化氢分子内成环反应、羟汞化及加汞化反应等。Chemosensors are highly valuable in a variety of fields such as environmental chemistry, analytic chemistry and bio-medicinal science. They provide accurate, on-line, and low-cost detection of toxic heavy metal ions with high selectivity and sensitivity. More and more attention is contributed to the development of analyte- specific reaction-based optical chemosensors. The progress that has been achieved for the reaction-based optical chemosensors of Hg^2＋ is reviewed. This paper follows a classification of the sensing systems based on chemical reactions. It comprises of mercury-promoted desulfurization and thiol elimination reactions, mercury-promoted intramolecular cyclization by desulfhydrylation, oxymercuration, mercuration reaction, etc.
