Bioinspired supramolecular nanosheets of zinc chlorophyll assemblies

Abstract Two-dimensional sheet-like supramolecules have attracted much attention from the viewpoints of their potential application as functional (nano)materials due to unique physical and chemical properties. One of the supramolecular sheet-like nanostructures in nature is visible in the self-assem...
