Based on Hg²⁺-promoted deprotection reaction of thioketal, a type of thioketal decorated conjugated polymer (PTS) with the feature of aggregation induced emission enhancement (AIEE) was successfully synthesized as fluorescent turn on probe for Hg²⁺. With the introduction of trace aqueous Hg²⁺, fluorescence of PTS in THF-H₂O mixture (water fraction of 98%) exhibited significant enhancement. The response was very fast with good selectivity towards Hg²⁺ due to the specific chemical reaction. Other common metal ions (Ag⁺, Cr³⁺, Al³⁺, Fe³⁺, Ca²⁺, Ni²⁺, Co²⁺, Pb²⁺, Cu²⁺, Zn²⁺, Mg²⁺, Fe²⁺, Mn²⁺, Cd²⁺, Ba²⁺, Li⁺, Na⁺ and K⁺) gave nearly no disturbance to the sensing process. Furthermore, the detection limit of Hg²⁺ reached 2.3 × 10⁻⁷ mol L⁻¹ for this sensing system.

基于Hg ²⁺促进的硫缩酮的脱保护反应，成功合成了一种具有聚集诱导发射增强（AIEE）特征的硫缩酮修饰的共轭聚合物（PTS）作为Hg ^2+的荧光探针。随着痕量Hg ²⁺水溶液的引入，PTS在THF-H ₂ O混合物（水含量为98％）中的荧光显着增强。由于特定的化学反应，反应非常快，对Hg ²⁺具有良好的选择性。其他常见金属离子（Ag ⁺，Cr ³⁺，Al ³⁺，Fe ³⁺，Ca ²⁺，Ni 2 ⁺，Co 2 ⁺，Pb 2 ⁺，Cu 2 ⁺，Zn 2 ⁺，Mg 2 ⁺，Fe 2 ⁺，Mn 2 ⁺，Cd 2 ⁺，Ba 2 ⁺，Li ⁺，Na ⁺和K ⁺）几乎没有干扰传感过程。此外，对于该感测系统，Hg ²⁺的检测极限达到2.3×10 ^-7  mol L ^-1。
