Takami, Tomohide , Ye, Tao , Arnold, Dennis P., Sugiura, Ken-ichi , Wang, Rongming , Jiang, Jianzhuang, & Weiss, Paul S. (2007) Controlled Adsorption Orientation for Double-Decker Complexes. Journal of Physical Chemistry Part C: Nanomaterials and Interfaces, 111(5), pp. 2077-2080.
Control of the molecular orientation of double-decker complexes comprised of rare-earth metals sandwiched with naphthalocyanine and porphyrin/phthalocyanine, at the interface of a graphite surface and 1-phenyloctane solution, has been demonstrated for the future application of molecular rotor assembly. Scanning tunneling microscope images clarified the internal structures of the top ligands. The observed images indicate that naphthalocyanine ligands were selectively adsorbed onto the graphite surface and the counterpart ligands of porphyrin/phthalocyanine were oriented off the surface. Control of the orientation of monolayers of mixed double-decker complexes has also been demonstrated.
Impact and interest:
Citation countsare sourced monthly fromand 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.
