A simple Schiff-base receptor 1 was prepared. It exhibits an %26quot;off on-type%26quot; mode with high sensitivity in the presence of Al3+ and shows a high association constant (5.89 x 10(6) M-2) toward Al3+ in DMSO-H2O (4:6 v/v) solution. The addition of EDTA to receptor 1.Al3+ complex quenches the fluorescent intensity, indicating that receptor 1 serves as a reversible chemosensor.
