Facing up to matters: Template-assisted cofacial assembly of a ring-shaped polyoxomolybdate cluster (MC) by an oligomeric p-phenylenebutadiynylene rigid rod molecule bearing ammonium ion pendant groups (PBn) allowed for the formation of an inorganic/organic one-dimensional (1D) nanoobject. Studies indicate that the 1D object most likely has a polypseudorotaxane structure (see picture), in which multiple MC rings are threaded by the PBn rod.
