由L-谷氨酸衍生的两亲分子（每个分子中含有三个酰胺）形成的螺旋双层膜诱导了单体染料吸收带附近的强激子耦合。相应的D-异构体的圆二色性光谱的镜像观察。相应的酯型两亲物不能产生螺旋，没有观察到类似的诱导作用。据推测，染料是螺旋排列在螺旋双层膜，导致在诱导的手性，即使在单体染料。
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.
