Description
Summary:Synthesis and characterization of amphiphilic ruthenium(II) complexes of the type [Ru(Cn)3].(PF6)2 (C = 4,4′-dialkyl-2,2′-bipyridine, n = 5–9) are studied. Aggregation behavior has been studied in aqueous and non aqueous media. [Display omitted] Synthesis and characterization of five amphiphilic ruthenium(II) complexes of the type [Ru(Cn)3].(PF6)2 (Cn = 4,4′-dialkyl-2,2′-bipyridine, n = 5(4,4′-dipentyl), 6(4,4′-dihexyl), 7(4,4′-diheptyl), 8(4,4′-dioctyl), 9(4,4′-dinonyl)) have been investigated. Single crystal X-ray structures of 4,4′-dipentyl-2,2′-bipyridine (C5), 4,4′-dioctyl-2,2′-bipyridine (C8) ligands and [Ru(C5)3](PF6)2 complex are elucidated. Structural inferences are corroborated through the density functional theory. Molecular aggregations in these systems in aqueous and non-aqueous media have further been analyzed from FESEM experiments.
