An Acylhydrazone-Based Fluorescent Sensor for Sequential Recognition of Al³⁺ and H₂PO₄.

ABSTRACT: A novel acylhydrazone-based fluorescent sensor NATB was designed and synthesized for consecutive sensing of Al³⁺ and H₂PO₄^-. NATB displayed fluorometric sensing to Al³⁺ and could sequentially detect H₂PO₄^- by fluorescence quenching. The limits of detection for Al³⁺ and H₂PO₄^- were determined to be 0.83 and 1.7 μM, respectively. The binding ratios of NATB to Al³⁺ and NATB-Al³⁺ to H₂PO₄^- were found to be 1:1. The sequential recognition of Al³⁺ and H₂PO₄^- by NATB could be repeated consecutively. In addition, the practicality of
