Abstract:
Understanding electron transport at the organic-inorganic interface is crucial for many research fields including surface physics and chemistry. In this article, we report the nonlocal chemical reactivity of one monolayer copper hexadecafluorophthalocyanine (F(16)CuPc) adsorbed on two different substrates, Ag(111) and Au(111), by injecting hot electrons from a scanning tunneling microscope tip. On the basis of experimental and theoretical results, the nonlocal reactions are proposed to strongly depend on hot-electron transport through molecule-substrate interface states. This observation of nonlocal reactivity increases our understanding of electron transport at organic-metal interfaces.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
