Amphiphilic polypyridyl ruthenium complexes: Synthesis, characterization and aggregation studies. (15th May 2019) - Bhand, Sujit
Graphical abstract: 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. Abstract: 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.
