WebThe process was repeated more than 20 times. Thus, both acidichromism and a chiroptical switch were realized in the complex film. A mechanism related to the cooperative loading of the dye into the LbL film, dye aggregation, conformational change of PLGA and their relationship with the supramolecular chirality of the film was discussed. WebFeb 21, 2024 · This chiroptical behavior can be repeated several times. Microscopy analysis showed that the supramolecular helices were assembled to form spheres. In addition to that, we also found that the handedness of supramolecular chirality is dependent on the position of Trp residues on the aromatic scaffold.
