Abstract

We have attempted to observe induced CD bands for supramolecular assemblies composed of typical (chiral) copper(II) complexes incorporating amino acid ligands (alanine and glycine, abbreviated as Cu-ala and Cu-gly, respectively) and typical chiral phospholipid, lecithin derivative (abbreviated as PL). It is a well-known biomaterial to form vecicles of lipid bilayers by self-assembly process. Although, we could measure normal CD spectra of the chiral copper(II) complex, whose absolute structures were also confirmed by X-ray crystallography before using the experiments, aqueous solutions of Cu-ala and PL or Cu-gly and PL did not appear expected CD bands. By comparing with other systems of our previous studies on chiral metal complexes exhibiting induced CD phenomenon, we discuss suitable conditions (or investigating causes of failure according to the aims and scopes of this journal) for these systems.
