A novel ruthenium(II) polypyridyl complex bearing 1,8-naphthyridine was successfully designed and synthesized. This complex was fully characterized by EI-HRMS, NMR, and elemental analyses. The recognition properties of the complex for various metal ions were investigated. The results suggested that the complex displayed high selectivity and sensitivity for Cu and Fe ions with good anti-interference in the CHCN/HO (1:1, /) solution. The fluorescent chemosensor showed obvious fluorescence quenching when the Cu and Fe ions were added. The detection limits of Cu and Fe were 39.9 nmol/L and 6.68 nmol/L, respectively. This study suggested that this Ru(II) polypyridyl complex can be used as a high selectivity and sensitivity fluorescent chemosensor for Cu and Fe ions.
