A new series of ligands containing the 2-(2-hydroxy-3- naphthyl)-4-methylbenzoxazole (HNBO) fluorophore showed selectivity for Mg 2+ ions, without the interference of Ca 2+ . The most promising representative L3 resulted the best performing sensor for Mg 2+ both in solution and embedded in an all-solid-state optode, especially towards real samples of drinkable water.
