A novel fluorescent probe molecule, 2-(anthracen-9-yl)-1,3-dithiolane (AADT), is designed and synthesized for Hg²⁺ detection successfully, based on a good aggregation induced emission (AIE) fluorescent mechanism and a specific reaction type. DMF-H₂O mixed solvent (F_w 80% V/V) is suitable to disperse AADT for forming 1 × 10⁻⁵ mol L⁻¹ solution with an AIE-active fluorescence probe system. Meanwhile, 9-Anthraldehyde also presents good fluorescence at same condition. With the increase of trace Hg (II), the AADT probe shows dual-channel, (turn-off at 429 nm, and turn–on at 511 nm) fluorescence probe character. (R² > 0.994), which does not interfere each other. The probe demonstrates excellent selectivity, anti-inference properties, and several metal ions and acid ions hardly affect its performance. The LOD of the AADT probe is lower than 2.34 × 10⁻⁸ mol L⁻¹, and proper to many common AIE-active probes.

基于良好的聚集诱导发射（AIE）荧光机理和良好的荧光光谱，设计并合成了新型的荧光探针分子2-（蒽-9-基）-1,3-二硫杂环戊烷（AADT），用于Hg ^2+的成功检测。具体的反应类型。DMF-H ₂ O混合溶剂（F _w 80％V / V）适用于分散AADT，以使用AIE活性荧光探针系统形成1×10 ^-5 mol L ^-1溶液。同时，9-蒽在相同条件下也显示出良好的荧光。随着痕量汞（II）的增加，AADT探针显示出双通道荧光探针特性（在429 nm处关闭，在511 nm处开启）。（R ² > 0.994），这不会互相干扰。该探针具有出色的选择性，抗干扰性，几种金属离子和酸性离子几乎不会影响其性能。AADT探针的LOD低于2.34×10 ^-8  mol L ^-1，适用于许多常见的AIE活性探针。
