Abstract: We report two ruthenium(II) polypyridyl complexes with pendant phenol/catechol functionality that act as colorimetric sensors for fluoride ions. Experiments have revealed that hydrogen bond formation occurs with a slight excess of fluoride ion. However, in higher [F-], deprotonation of the O-H functionality resulted. Time-dependent (TD-DFT) calculations at the B3LYP/LANL2DZ level have shown that new bands appear at longer wavelengths upon complexation with fluoride ions. These are of mixed character, MLCT (dÏ€(Ru) → Ï€*(Li/bpy)), and intra- and interligand [Ï€(L 1) → Ï€*(bpy) and Ï€(L1) → Ï€*(L1)] transitions. These complexes also act as sensors for fluoride ions in solvent-water mixtures. © 2007 American Chemical Society.
