| Abstract
| - A series of novel organic superstructures exhibiting diverse aggregate morphologies with liquid-crystalline-like properties were prepared by a simple precipitation method. Here, a chiral sugar moietywas simply introduced at the Schiff-based rod end of rod−coil molecules. In contrast to coil−coilmolecules, the self-assembled rod−coil molecules exhibit a high segregation strength for phase separationbecause of their liquid-crystalline-like behavior. The morphological transformation of self-assembledchiral Schiff-based rod−coil amphiphiles, from a platelet-like morphology to helical twists, was obtainedby increasing the length of the hydrophobic tail. Consistent with theoretical predictions, the bendingforce from the chiral entity depends on the size of the adjacent hydrophobic tail. That is, the size ofhydrophobic chain determines the threshold of bending for the formation of a helical morphology.Moreover, by introducing an additional tethered hydrophobic chain self-assembled spherical vesiclescan be obtained through the collapse of the twisted shape.
