Multiple chirality inversion of pyridine Schiff-base cholesterol-based metal-organic supramolecular polymers.

Based on a metal coordination driven co-assembly strategy, a metal-organic supramolecular polymer system of pyridine Schiff-base cholesterol and metal ions with multiple supramolecular chirality inversion was successfully achieved by the stoichiometry and exchange of metal ions (such as Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , and Ag + ), as well as the solvent polarity.
