摘要

Quinolinyl-azo-naphthol (HL) is a selective turn-on chemosensor for Al3+ in the presence of other ions and the excitation at visible light (537 nm) shows a 750 fold enhancement of emission at 612 nm. The limit of detection (LOD) is 0.69 nM (3σ method), which is far below the WHO recommended value for Al3+ in drinking water (7.41 μM). The composition of the isolated complex [AlL2]+ is supported by ESI-MS spectral data and Job's plot. Upon addition of aqueous F− to the [AlL2]+ solution the emission intensity is quenched and the LOD of F− is 0.63 nM. HL is thus instrumental for the design of portable kits for the detection of fluoride contamination in drinking water. The probe undergoes azo-hydrazo tautomerization and also exhibits an INHIBIT logic gate with Al3+ and F− as chemical inputs by monitoring the emission mode at 612 nm.

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
