Surface-assisted dehydrogenative homocoupling of porphine molecules.
The templated synthesis of porphyrin dimers, oligomers, and tapes has recently attracted considerable interest. Here, we introduce a clean, temperature-induced covalent dehydrogenative couplingExpand

Uracil on Cu(110): a quantitative structure determination by energy-scanned photoelectron diffraction.
The local adsorption site of the nucleobase uracil on Cu(110) has been determined quantitatively by energy-scanned photoelectron diffraction (PhD). Qualitative inspection of the O 1s and N 1s softExpand

How surface bonding and repulsive interactions cause phase transformations: ordering of a prototype macrocyclic compound on Ag(111).
We investigated the surface bonding and ordering of free-base porphine (2H-P), the parent compound of all porphyrins, on a smooth noble metal support. Our multitechnique investigation reveals aExpand

Asymmetric photoelectron transmission through chirally-sculpted, polycrystalline gold.
Strong circular dichroism is observed in core-level photoelectron transmission through a chirally-etched polycrystalline Au surface, consistent with a chiral dependence on the electron's orbitalExpand

Synthesis of Pyrene-Fused Pyrazaacenes on Metal Surfaces: Toward One-Dimensional Conjugated Nanostructures.
We investigated the synthesis of one-dimensional nanostructures via Schiff base (imine) formation on three close-packed coinage metal (Au, Ag, and Cu) surfaces under ultrahigh vacuum conditions. WeExpand

Surface-Assisted Cyclodehydrogenation; Break the Symmetry, Enhance the Selectivity.
Selectivity in chemical reactions is a major objective in industrial processes to minimize spurious byproducts and to save scarce resources. In homogeneous catalysis the most important factor whichExpand

Water does partially dissociate on the perfect TiO2(110) surface : a quantitative structure determination
There has been a long-standing controversy as to whether water can dissociate on perfect areas of a TiO2(110) surface; most early theoretical work indicated this dissociation was facile, whileExpand

Sub-picosecond fluorescence evolution of amino-cyano-stilbenes in methanol: polar solvation obeys continuum theory without evidence of twisting.
The spectral evolution of fluorescence from 4-(dimethylamino)-4'-cyanostilbene (DCS) in methanol, and of two derivatives bearing either the anilino (ACS) or the julolidino (JCS) moiety, was measuredExpand

Corrugation in the Weakly Interacting Hexagonal-BN/Cu(111) System: Structure Determination by Combining Noncontact Atomic Force Microscopy and X-ray Standing Waves.
Atomically thin hexagonal boron nitride (h-BN) layers on metallic supports represent a promising platform for the selective adsorption of atoms, clusters, and molecular nanostructures. Specifically,Expand
