Synthesis, characterisation and in vitro cytotoxicity of mixed ligand Pt(ii) oxadiazoline complexes with hexamethylenetetramine and 7-nitro-1,3,5-triazaadamantane.

trans-Platinum(ii) oxadiazoline complexes with 7-nitro-1,3,5-triazaadamantane (NO-TAA) or hexamethylenetetramine (hmta) ligands have been synthesised from trans-[PtCl(PhCN)] via cycloaddition of nitrones to one of the coordinated nitriles, followed by exchange of the other nitrile by NO-TAA or hmta. Stoichiometric control allows for the selective synthesis of mono- and dinuclear complexes where 7-NOTAA and hmta act as mono- and bidentate ligands, respectively. Precursors and the target complexes trans-[PtCl(hmta)(oxadiazoline)], trans-[PtCl(NO-TAA)(oxadiazoline)] and trans-[{PtCl(oxadiazoline)}(hmta)] were characterised by elemental analysis, IR and multinuclear (H, C, Pt) NMR spectroscopy.

Conducting core-shell nanowires by amyloid nanofiber templated polymerization.

The preparation of conducting polymer nanowires in aqueous solutions is a challenging goal, especially for applications in nanobioelectronics. Here, we show that amyloid nanofibers template the formation of conducting polyaniline nanowires with a core-shell architecture. The nanofibers exhibit hydrophobic pockets that presumably preassemble the aniline monomers.
