摘要：Nanoparticle-mediated intervalence transfer was first reported with ferrocene moieties that were attached onto the ruthenium nanoparticle surface by ruthenium=carbene p bonds. The resulting particles exhibited two pairs of voltammetric waves with a potential spacing of about 200 mV, and a rather intense absorption peak in the near-infrared range (~1930 nm) at mixed valence. Quantum calculations based on density functional theory showed that the nanoparticle core electrons served as conducting band states for the effective charge delocalization between particle-bound ferrocene moieties. These studies provide a first and direct confirmation of Hush’s hypothesis made four decades ago that interfacial intervalence transfer might occur if the moieties were immobilized onto the electrode surface through a conjugated linker.
