For tailoring charge transfer (CT) complexes in bilayer membranes, single-chain bilayer-forming amphiphiles, having a hydrophilic viologen head and a hydrophobic aromatic segment, such as an azobenzene or a biphenyl group, were prepared. Bilayer membranes with a titled molecular orientation were formed when the amphiphiles which had five carbon atoms in the spacer methylene chain between the viologen head and the aromatic segment were dissolved in water. A visible absorption band at 460 nm, which was attributed to the CT interaction between the viologen head and the biphenyl segment of the adjacent molecule in the two-dimensional molecular array, was newly observed in the bilayer membrane.
