Self-assembly of a halogenated molecule on oxide-passivated Cu(110)
El Garah, Mohamed, Lipton-Duffin, Josh, MacLeod, Jennifer M., Gutzler, Rico, Palmino, Frank, Luzet, Vincent, Chérioux, Frédéric, & Rosei, Federico (2013) Self-assembly of a halogenated molecule on oxide-passivated Cu(110). Chemistry - An Asian Journal, 8(8), pp. 1813-1817.
The supramolecular self-assembly of brominated molecules was investigated and compared on Cu(110) and Cu(110)[BOND]O(2×1) surfaces under ultrahigh vacuum. By using scanning tunnelling microscopy, we show that brominated molecules form a disordered structure on Cu(110), whereas a well-ordered supramolecular network is observed on the Cu(110)[BOND]O(2×1) surface. The different adsorption behaviors of these two surfaces are described in terms of weakened molecule–substrate interactions on Cu(110)[BOND]O(2×1) as opposed to bare Cu(110). The effect of oxygen-passivation is to suppress debromination and it can be a convenient approach for investigating other self-assembly processes on copper-based substrates.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
