A new combinatorial library of fluorescent materials was prepared by covalent anchoring of 1-pyrene and 1-methylpyrene bichromophores to Merrifield and Wang resins functionalized with alkyl diamine spacers and its sensing properties toward Pb2+, Cd2+ and Hg2+ were evaluated in water. It was found that the Wang resin modified with ethane-1, 2-diamine as spacer and functionalized with the 1-pyrene bichromophore senses selectively Pb2+ with an enhancement of fluorescence intensity. The detection limit and the percentage of sorption were determined as 29.6 μM and 80.3%, respectively.
