Coalescence of 3-phenyl-propynenitrile on Cu(111) into interlocking pinwheel chains.
نویسندگان
چکیده
3-phenyl-propynenitrile (PPN) adsorbs on Cu(111) in a hexagonal network of molecular trimers formed through intermolecular interaction of the cyano group of one molecule with the aromatic ring of its neighbor. Heptamers of trimers coalesce into interlocking pinwheel-shaped structures that, by percolating across islands of the original trimer coverage, create the appearance of gear chains. Density functional theory aids in identifying substrate stress associated with the chemisorption of PPN's acetylene group as the cause of this transition.

An ab initio insight into the Cu(111)-mediated Ullmann reaction.
The coupling process of phenyl radicals-the important intermediates in the prototypal Ullmann reaction-on Cu(111) is addressed using density functional theory. Consistent with experiments, we prove that the fragments interact attractively already at relatively large distances. An intermediate state involving a "popping-out" surface atom is reached through a non-trivial surface diffusion path. T...
متن کاملA new on-surface synthetic pathway to 5-armchair graphene nanoribbons on Cu(111) surfaces.
We report a new pathway to fabricate armchair graphene nanoribbons with five carbon atoms in the cross section (5-AGNRs) on Cu(111) surfaces. Instead of using haloaromatics as precursors, the 5-AGNRs are synthesized via a surface assisted decarboxylation reaction of perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA). The on-surface decarboxylation of PTCDA can produce extended copper-perylen...

In the title complex, [Cu(C(12)H(12)N(3)O)(2)], the Cu(II) ion is tetra-coordinated by two N atoms and two O atoms from two bis-chelating 4-(1-imino-eth-yl)-3-methyl-1-phenyl-1H-pyrazol-5-olate ligands in a square-planar geometry. The two N atoms and two O atoms around the Cu(II) atom are trans to each other, as the Cu(II) atom lies on an inversion centre. The six-membered ring composed of the ...
متن کاملInterchain Interactions Mediated by Br Adsorbates in Arrays of Metal Organic Hybrid Chains on Ag(111)
Metal organic hybrid structures have attracted much attention due to possible applications including gas storage, heterogeneous catalysis, andmolecular separation. Hybrid structures are primarily synthesized in solution phase but can be grown under vacuum conditions. On metal surfaces, it has been reported that onedimensional (1-D) metal organic hybrid chains were grown via catalytic self-assem...
متن کاملCoverage-driven dissociation of azobenzene on Cu(111): a route towards defined surface functionalization.
We investigate the surface-catalyzed dissociation of the archetypal molecular switch azobenzene on the Cu(111) surface. Based on X-ray photoelectron spectroscopy, normal incidence X-ray standing waves and density functional theory calculations a detailed picture of the coverage-induced formation of phenyl nitrene from azobenzene is presented. Furthermore, a comparison to the azobenzene/Ag(111) ...
