Özet
Novel ruthenium(II)bpy complexes of the phenanthrimidazole-pendant cyclen and cyclam macrocyclic ligands were synthesized as inorganic host molecules. Inorganic host design was planned as a "complex ligand" form because of its tetraaza macrocyclic unit, which has the ability to coordinate to the metals. Photophysical properties and metal selectivity of inorganic hosts RuL1A and RuL2 complex ligands were investigated by UV-vis and fluorescence spectroscopy in aqueous medium. Among Ag(I), Li(I), Na(I), K(I), Cd(II), Cr(II), Fe(II), Hg(II), Ni(II), Pb(II), Zn(II), Cu(II), Mn(III), and Co(III) metal ions, Fe(II) addition causes spectral changes for both RuL1A and RuL2 complex ligands. Electrochemical studies were performed for RuL1B and also for cis-[Ru(bpy)(2)Cl-2]. Bimetallic complexes [[Ru(bpy)(2)([Ni(2-(4-((1,4,8,11-tetraazacyclotetradecan-1-yl)methyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline])](ClO4)(4), RuL1-NiA and [Ru(bpy)(2)([Ni(2-(4-((1,4,8,11-tetraazacyclotetradecan-1-yl)methyl)phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline])]Cl-4, RuL1-NiB solid complexes were also obtained by the reaction of the RuL1B and Nickel(II).
