Russian dolls partially formed through the use of diffusion‐ordered spectroscopy are described by C. L. Raston et al. in the Full Paper on page 2772 ff. Such arrangements have been used to assemble nanometer‐scale cuboctahedral spheroids in the solid state; these results suggest that the build‐up mechanism would be “molecular capsule” to “cuboctahedron”, given the binding of a sodium [18]crown‐6 complex by p ‐sulfonatocalix[4]arene ( K a ≈3.1×10 3 M −1 ), and that the cuboctahedra assemble with lanthanide [18]crown‐6 guest species.
