Edge-on bonding of benzene molecules in the second adsorbed layer on Cu(110)

Article Abstract:

The bilayer of benzene on Cu(110) is studied with temperature-programmed desorption (TPD), time-of-flight electron simulated desorption ion angular distribution (TOF-ESDAID), and scanning tunneling microscopy (STM). The ESDAID and STM studies have observed flat-lying benzene molecules in the alpha layer on Cu(110) and the multilayer forming on top of the (alpha+beta) bilayer has displayed completely random C-D bond orientation.

Assembly of linear clusters of iodobenzene dimers on Cu(110)

Article Abstract:

Low-temperature STM observations of the low-coverage chemisorption behavior of iodobenzene on Cu(110) are presented at two annealing temperatures. A model is proposed in which iodine atoms on each member of the pair are directed toward one another. The driving force for the formation of such clusters is suggested to be the dispersion interactions between the polarizable indobenzene molecules.

Phenyl species formation and preferential hydrogen abstraction in the decomposition of chemisorbed benzoate on Cu(110)

Article Abstract:

The temperature-programmed reaction spectroscopy and scanning tunneling microscopy are used to investigate the adsorption and decomposition of benzoic acid on the Cu(110) surface. The results show that the mobile phenyl species is surface bound and preferentially attacks C-H bonds that are nearest the Cu surface and bind the benzoate species as either an upright species or a tilted species.
