Abstract

A series of ruthenium(II) diimine complexes containing thia-, selena- and aza-crowns derived from 1,10-phenanthroline have been synthesized and characterized, and their photophysics and electrochemistry were studied. Their interaction with metal ions was investigated by UV-vis, luminescence, and ¹H NMR spectroscopy. The crystal structures of [Ru(bpy) ₂(L1)](PF₆)₂, [Ru(bpy)₂(L2)] (ClO₄)₂, [Ru(bpy)₂(L3)](ClO₄) ₂, and [Ru(bpy)₂(L4)](ClO₄)₂ have been determined. The luminescence properties of [Ru(bpy)₂(L1)] (ClO₄)₂ were found to be sensitive and selective toward the presence of Hg²⁺ ions in an acetonitrile solution. The addition of alkaline-earth metal ions, Zn²⁺, Cd²⁺, and Hg ²⁺ ions, to the solution of [Ru(bpy)₂(L6)](ClO ₄)₂ in acetonitrile gave rise to large changes in the UV-vis and emission spectra. The binding of metal ions to [Ru(bpy) ₂(L6)](ClO₄)₂ was found to cause a strong enhancement in the emission intensities of the complex, with high specificity toward Hg²⁺ ions.
