Fluorescent probes for selective determination of trace level Al3+: recent developments and future prospects

Abstract

Developments in the field of fluorescent chemosensors for trace level determination of Al³⁺ have been described. Design, synthesis and applications of Al³⁺ selective fluorescent sensors have attracted a great deal of attention due to their versatile and emerging biological implications. A systematic description of different fluorescent probes based on their fluorophore skeleton has been made. The sensing mechanism of each fluorescent probe has been briefly discussed. Special emphasis has been given to consideration of the greenness of the methods, particularly, the use of greener solvents like water. The review covers published work on fluorescence sensing of Al³⁺ worldwide together with our own contribution in this field.
