摘要

A novel colorimetric and fluorometric chemosensor for Hg²⁺ detection is designed and synthesized based on poly (p-phenyleneethynylene) containing benzo [2, 1, 3] thiadiazole (PPE-BDT). A highly Hg²⁺-selective fluorescence quenching property in combination with a visible colorimetric change of solution from yellow to violet can be observed, and it shows that PPE-BDT can serve as a sensitive "naked-eye" indicator for Hg²⁺. The coordination of Hg²⁺ to the sulfur atom of benzo [2, 1, 3] thiadiazole leads to inter-chain π-π interactions, thus it is responsible for the significant variations on the photophysical properties of the polymer.
