Abstract

A simple Al³⁺ sensor, 8-acetyl-7-hydroxy-4-methylcoumarin (AHMC), was synthesized. It can display an excellent fluorescence “turn-on” response to Al³⁺ over other common metal ions in methanol–water media. Theoretical calculations have also been carried out to understand the configuration of the AHMC–Al complex and rationalize experimental absorption data.
