Summary: We synthesized a biphenyl-derived amido Schiff base, sensor 1, which has hard donors for chelating with hard metal centers. The crystal structure of sensor 1 shows various types of H-bond interactions that stabilize the crystal lattice. Sensor 1 exhibits high selectivity and sensitivity towards Al3+ ions in aqueous DMF media. We also reported the first structurally characterized six-coordinate dinuclear Al3+ complex, complex 1, in which each Al3+ ion is hexa-coordinated and the sodium ion is penta-coordinated in a highly distorted trigonal bipyramidal geometry. Sensor 1-coated test kits successfully detected Al3+ ions under UV light.

Summary: In this study, a turn-on fluorogenic chemosensor HMBP was designed to detect Al3+. The chemosensor showed high sensitivity and binding capacity towards Al3+, with a stoichiometric ratio of 1:2 and a binding constant of 1.21 x 10(8) M-1. The response of the chemosensor to Al3+ was attributed to blocking the PET and C=N isomerisation mechanisms. The sensor was successfully employed for the determination of Al3+ in real food samples, drinking waters, and herbal teas.

Summary: The ability of the new furfurylamine-derived Schiff base ligand CFMP to recognize Cd2+ ions as a chemosensor has been studied. The CFMP demonstrated selective colorimetric and fluorescence sensing behavior towards the Cd2+ ion in a methanol-water system with strong binding nature, easily visible to the human eye. Job's plot titrations and LCMS data confirmed the stoichiometry and complexation of the metal-ligand system, while fluorescence characteristics showed improved emission intensity upon complexation. Detection of Cd2+ ions in real water samples was also investigated.
