In recent years, fluorescent chemosensors have attracted significant interest because of their potential use in medicinal
and environmental research. The most commonly employed method used for chemosensor detection is the development of
probe molecules that consist of a photon interaction site as a fluorophore and a metal binding site. In the presence of specific
metal ions, the fluorophore−receptor communication gets turned on as a result of the binding of the metal ions at the
receptor site. Until recently, only a few fluorescent chemosensors have been developed for detection of Al3+
