Chiral Transformation of Achiral J‐aggregates of a Cyanine Dye Templated by Human Serum Albumin

Abstract

Double-minded supramolecules: The interactions between human serum albumin (HSA) and J-aggregation of a cyanine dye (PTC) in phosphate buffer solution are studied. In the presence of HSA, the achiral J-aggregate shows chirality. The chirality can be inversed by adjusting the ratio of HSA to PTC and the pH value (see picture; CD=circular dichroism).
