Highly sensitive salicylic fluorophore for visual detection of picomole amounts of Cu2+?
RSC Advances Pub Date: 2013-10-31 DOI: 10.1039/C3RA44239J
Abstract
Four new fluorophores containing multiple fluorogenic branches of phenylene-ethynylene and salicylic acid Cu2+ binding sites are synthesized and evaluated as Cu2+ sensors in aqueous media. The fluorophore, F4, having a triphenylamine core and three fluorogenic branches, possesses superior sensitivity, selectivity and emission properties for fluorescence quenching detection of Cu2+. This fluorophore exhibits the highest Cu2+ quenching sensitivity in aqueous solution; Ksv = 5.79 × 106 M?1. The relatively high fluorescence emission of this fluorophore provides excellent visual contrast in a solid state paper-based sensor that enables naked eye detection of Cu2+ at the picomole level.
