The extended 1D tungstophosphite molecular wire is obtained by connection of polyoxometalates. Self‐assembly of a triangular P III O 3 unit with tungstate produces a hexagonal [HP III W 6 O 21 ] 2− building block, which then connects linearly to form the molecular wire. The surface property of the molecular wire is tuned to hydrophobic using organoammonium cations, and the surface‐modified material disperses easily in organic media. The multifunctional material, which possesses nanostructure, hydrophobicity, and redox properties simultaneously, is suitable for olefin epoxidation in organic solvent.
