Abstract
Taking a natural triterpenoid as the building block, we have regulated a pyridinium-functionalized methyl glycyrrhetate (C4-MGP) into P-type helices in water primarily driven by hydrophobic forces. By analysing their temperature-dependent CD and UV-Vis spectra, these hierarchical chiral assemblies were found to be formed in a cooperative supramolecular polymerization manner.
