Abstract
A coumarin-based “Turn-on” fluorescence chemosensor 1 containing L-histidine for Al3+ was readily synthesized and investigated, which showed high selectivity and remarkable sensitivity to aluminium(III) ions based on a photo-induced electron-transfer (PET) mechanism in aqueous solution (Tris–HCl, 0.1 mM, pH 7.2). The sensor responded rapidly to Al3+ in aqueous solutions with a 1?:?1 stoichiometry. Meanwhile, it showed excellent adaptability and also responsiveness.
