| dc.description.abstract | Two viologen compounds incorporating mono-methyl viologen and mono-methyl bis-viologen terminated with acetyleacetone moieties: C1V2+A.2PF6- and C1V24+A.4PF6- respectively are synthesized. These viologens are characterized by 1H-NMR, FT-IR and mass spectrometries and thermal analyses. The soluble complexes of Fe2+, Cu2+ and Zn2+ are formed with C1V2+A.2PF6- and C1V24+A.4PF6- ligand in MeCN media and confirmed by UV-Visible absorption spectroscopy titrations. The redox-responsive switches are triggered through reduction by solvation in DMF for first time and also by activated zinc powder under argon atmosphere. Complexes of acetylacetone and 3-chloroacetylacetone with Cu2+ ion: CuA and CuA-Cl respectively are synthesized and characterized by FT-IR, mass and UV-Visible absorption in different solvents, XRD spectrometries and thermal analyses. The reduction of these complexes with 4,4`-bipyridine at lab temperature afforded solid adduct complexes CuABpy and CuA-ClBpy respectively. The interaction of Cu2+-complexes with 4,4`-bipyridine in solution affording adducts are investigated by absorption spectroscopy. Also, interaction of Cu2+-complexes with propylene spacered bis-viologens V22+.2PF6- in solution are investigated. Novel molecules switches are obtained by reduction of viologen unites within adduct structures in solution. The extraction of Cu2+ ion by 3-chloroacetylacetone are performed following two procedures: solvent extraction and cloud point extraction. | |
