Abstract

We propose a new strategy that the nano-layer and nano-film structures built on two types of metal complexes, [Co^III{ph(bu) ₂(L)₂}]^- (ph(bu)₂: o-phenylenebisbiuretato, L: axial ligands) and [Ni^II(bpbg) ²] (bpbg: biphenylbiganidato). These structures have been formed by self-assembling with hydrogen bonding interactions. The crystal structures of [Co^III{ph(bu)₂(L)₂}]^--[Ni ^II(bpbg)₂] have revealed to provide a channel structure changeable according to the size or shape of guest cation molecules. While, treatment of [Co^III{ph(bu)2}]^- with C18MeIm⁺ (C18MeIm⁺: 1-octadecyl-3-methylimidazolium) in an aqueous solution gave a fluid and metallic silver-colored solution of self-organized membranes. The scanning electron micrographic observation showed the rectangle-shaped nano-film structure (ca. 15 nm hight and 1-6 mm width), suggesting the formation of organic-inorganic composite membrane of [Co^III{Ph(bu) ₂}]^- and C18MeIm⁺.
