Abstract

A simple Schiff-base receptor 1 was prepared. It exhibits an "off-on-type" mode with high sensitivity in the presence of Al ^{3 +} and shows a high association constant (5.89 × 10 ⁶ M^{- 2}) toward Al^{3 +} in DMSO-H₂O (4:6 v/v) solution. The addition of EDTA to receptor 1·Al^{3 +} complex quenches the fluorescent intensity, indicating that receptor 1 serves as a reversible chemosensor. Crown
