Herein, we report a new benzothiazole-based azomethine receptor L as a reversible fluorescent sensor for the selective detection of Al3+ in buffered aqueous methanol (20 mM HEPES, pH = 6.0, 50% (v/v) CH3OH). The fluorescence enhancement response of L towards Al3+ along with a large blue shift (Δλ = ∼157 nm) may be attributed to the formation of the L–Al3+ complex, which results in the inhibition of excited state intramolecular proton transfer (ESIPT) and CN isomerisation as well as the chelation enhanced fluorescence (CHEF). The results of Job's plot and mass spectroscopic analysis support the 1 : :1 stoichiometry of the complex between L and Al3+ ions. The proposed complex structure was calculated by applying the DFT method. Furthermore, the applicability of the probe has been tested in BEL-7402 human hepatoma carcinoma cells under a fluorescence microscope, where turn-on, intense bluish green fluorescence was observed in the presence of Al3+ ions.

Analytical Methods

Analytical Methods welcomes early applications of new analytical and bioanalytical methods and technology demonstrating the potential for societal impact. We require that methods and technology reported in the journal are sufficiently innovative, robust, accurate, and compared to other available methods for the intended application. Developments with interdisciplinary approaches are particularly welcome. Systems should be proven with suitably complex and analytically challenging samples. We encourage developments within, but not limited to, the following technologies and applications: global health, point-of-care and molecular diagnostics biosensors and bioengineering drug development and pharmaceutical analysis applied microfluidics and nanotechnology omics studies, such as proteomics, metabolomics or glycomics environmental, agricultural and food science neuroscience biochemical and clinical analysis forensic analysis industrial process and method development
