Solution superstructures: truncated cubeoctahedron structures of pyrogallol[4]arene nanoassemblies

Abstract

Giant nanocapsules: the solution-phase structures of PgC₁Ho and PgC₃Ho have been investigated using in situ neutron scattering measurements. The SANS results show the presence of spherical nanoassemblies of radius 18.2 Å, which are larger than the previously reported metal-seamed PgC₃ hexamers (radius = 10 Å). The spherical architectures conform to a truncated cubeoctahedron geometry, indicating formation of the first metal-containing pyrogallol[4]arene-based dodecameric nanoassemblies in solution.
