摘要
A novel quinoline-coumarin (QC) fluoroionophore conjugated by means of a triazolyl-pyrrolidinyl linker exhibits differential dual selectivity for Zn(2+) and Al(3+) in mixed media. QC acts as a turn on fluorescence sensor for Zn(2+) while exhibiting overall ratiometric selectivity for Al(3+) in aqueous media. Moreover, QC exhibited preferential second mode of selectivity for Al(3+) as it ratiometrically displaces Zn(2+) from the [QC + Zn(2+)] complex.
