The effect of delta lambda chirality on molecular organization in two-dimensional films of a Ru(II) complex with a mesogenic ligand.
A novel amphiphilic Ru(II) complex, [Ru(acac)2L] (acac = acetylacetonato, L = 5,5'-bis(4-octylphenyloxycarbonyl)-2,2'-bipyridyl), in which L undergoes SmC, SmA and N liquid crystal phases, exhibits a remarkable chirality effect on its monolayer state: that is, a racemic mixture gives a monolayer consisting of spike-like aggregates of 1.2 nm (in height) x 50 nm (in diameter), whereas the delta-enantiomer gives a uniform monolayer.
