Supramolecular Stereomutation in Kinetic and Thermodynamic Self-Assembly of Helical Merocyanine Dye Nanorods

An inversion of the exciton chirality and structural changes upon transformation from kinetic to thermodynamic assembly are features of helical bis(merocyanine) dye nanorods (see picture), as elucidated by time‐dependent circular dichroism (CD) spectroscopy and atomic force microscopy.
