Summary:A novel efficient terpyridine-based colorimetric fluorescent compound, TPI , based on the Wittig reaction, was synthesized and impregnated on filter paper into test strips, which could be applied to naked-eye sensing of mercuric ions (Hg 2+ ) in aqueous media through varied emission color from bright blue to yellow. TPI , with nitrogen from pyridine and oxygen from ether, had a high degree of water solubility and a strong coordination ability to Hg 2+ . Importantly, the test strips can be used to qualitatively trace amounts of hazardous Hg 2+ in various water samples and drinks. TPI , a novel colorimetric fluorescent compound prepared for test strips, can be used for naked-eye detection of Hg 2+ in tap water samples and drinks conveniently.
