中文摘要：

二根比色的探针基于为 Hg2+ 的察觉的 oxazine-thione 1a 和 1b 被设计并且综合。关于在荧光和一种颜色的 70 褶层改进的探查 1a 展览在 acetonitrile/wate 溶剂在 Hg2+ 的增加以后变化。1a 对在另外的金属离子上的 Hg2+ 也高度选择。而且， DFT/TDDFT 计算被拿向在离开上解释排放反应。

英文摘要：

Two colorimetric probes based on oxazine-thione la and lb for the detection of Hg2＋ were designed and synthesized. The probe la exhibits about a 70-fold enhancement in fluorescence and a color change alter the addition of Hg2＋ in acetonitrile/wate solvent, la was also highly selective to Hg2＋ over other metal ions. Furthermore, DFT/TDDFT calculations were taken to explain the OFF-ON emission response.
