Construction of Ru(II) Polypyridyl Based Macrocycles: Synthesis, Characterization, Electrochemical, Li Binding, Antitumour and Anti-HIV properties.

Some ruthenium (II) polypyridyl complexes with a bis-chalcone (obtained by the condensation of 3-methyl-thiophene-2-carboxaldehyde and 4-acetyl pyridine) have been synthesized and characterized spectroscopically (IR, NMR, UV/Vis), conductimetric, elemental analysis and FAB mass data. Their luminescent, redox and Li(+) binding properties have been studied. The anti-HIV and antitumour activities have also been reported.
