Figure. (A) Alternant (naphthalene) and non-alternant (azulene) π-electron systems on a copper (111) surface with experimental adsorption heights from NIXSW measurements (B,C) and adsorption energies from TPD (D). (E) Photoelectron spectroscopy (XPS, UPS) and (F) NEXAFS reveal details of the surface chemical bond, which depends strongly on the topology of the conjugated π-electron systems.
