Thioamide, urea and thiourea bridged rhenium(I) complexes as luminescent anion receptors
摘要:
Thioamides, urea and thiourea derivatives of 2,6-pyridinedicarbonyl dichloride, isophthaloyl dichloride and terephthaloyl dichloride have been synthesized. These ligands have been incorporated in dinuclear rhenium(I) diimine tricarbonyl complexes and the anion recognition properties of these complexes have been studied by luminescence, UV-Vis and (1)H NMR spectroscopic methods. The complexes act as receptors for anions via hydrogen bonding and electrostatic interactions. The anion sensing properties of the complexes are compared to earlier amide-based dinuclear rhenium(I) tricarbonyl complexes. (C) 2011 Elsevier B. V. All rights reserved.

ligands have been incorporated in dinuclear rhenium(I) diiminetricarbonyl complexes and provide anion recognition properties in these complexes. Furthermore, the related rhenium(I) complex featuring sulfonamide interacting sites that incorporate the highly chromophoric π-conjugated quinoxaline moiety has been prepared, characterized, and its photophysical properties were also studied.
