Abstract

A simple Schiff-base receptor 2 was prepared. It exhibits an "off-on-type" mode with high sensitivity in the presence of Al ³⁺. The receptor 2 exhibited a high association constant with submicromolar detection for Al³⁺ in EtOH-H₂O (95 : 5 v/v) solution. The addition of EDTA quenches the fluorescence of the receptor 2·Al³⁺ complex offering receptor 2 as a reversible chemosensor.
