Abstract

Three probes for Al³⁺ detection by both fluorescence and the naked eye in acetonitrile solution were developed. The mechanism of fluorescence was based on the aluminum complexation with rhodamine and subsequent Al³⁺-promoted hydrolysis of the Schiff base. Theoretical calculations indicated that the aluminum complexes tend to hydrolyze to compound L₆. A simple paper test strip system for the rapid monitoring of Al³⁺ was developed, indicating its convenient use in environmental samples.
