Abstract
Strong exciton coupling around the absorption band of monomeric dyes was induced by helical bilayer membranes formed from various L-glutamic acid-derived amphiphiles which contain three amides per molecule. The mirror-image of the circular dichroism spectra was observed by the corresponding D-isomers. No similar induction was observed by the corresponding ester-type amphiphiles which could not produce helices. It is assumed that dyes are helically arranged on helical bilayer membranes, resulting in an induction of chirality even in monomeric dyes.
