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.
