Resorcarene-Based Nanoarchitectures: Metal-Directed Assembly of a Molecular Loop and Tetrahedron

Large cavities and portals are present in the nanoscale molecular architectures formed from dithiocarbamate‐functionalized resorcarene ligands and zinc(II) or copper(III) ions. With ZnII a molecular loop based on a triangle of resorcarene cups is prepared—the cavity is circular (shown on the left). A molecular cage based on a distorted tetrahedron of four resorcarene ligands assembled by eight CuIII ions contains triangular‐shaped portals suitable for guest passage (shown on the right).
