Abstract:
A well-defined multidentate polycationic diblock copolymer with multiple quaternary ammonium and sulfonium groups is judiciously synthesized via living radical polymerization. This polymer can serve as a strong passivating ligand to replace the short ligand on a perovskite nanorod, thereby significantly enhancing its colloidal stability, moisture stability, photostability and thermal stability.
