A new Methoxy poly(ethylene glycol)-anchored polymer sensor P1, which contains anthracene fluorephore and di-2-picolylamine metal ions binding site, has been easily synthesized by "click reaction". In pure aqueous solution, P1 can coordinate with Hg2+ quickly to form 1:1 stoichiometry P1-Hg2+ complex, with quenching the fluorescence of P1. In addition, P1-Hg2+ shows exclusive fluorescence turn-on sensing of cysteine (Cys) over other amino acids for the displacement method.

Key words: PEG, fluorescence, Cys recognition, anthracene, Hg2+
