A full picture of the crystallographic and electronic structure of PEN and F 16CuPC monolayers as well as of their 1:1 binary mixture on the Au(111) surface has been explored by means of a variety of surface-sensitive techniques, providing important information on the intermolecular and molecule-substrate interactions governing the self-assembly process. A long-range ordered donor-acceptor network is observed for the mixture as a result of the greatly enhanced intermolecular interaction via C-F···H-C hydrogen bonds. Interestingly, the new supramolecular structure involves changes in the electronic structure of the molecular components. In particular, the strongest changes are observed at the C and F atoms of the F 16CuPc, as opposed to the F 16CuPc N, Cu, or PEN C atoms. With the aid of theoretical calculations, such effects are found to be at least partially related to an upward shift in energy of the F 16CuPc molecular orbitals, concomitant with a molecule-to-metal charge donation, not from the HOMO, but deeper lying orbitals. © 2012 American Chemical Society. | Versión del editor: | http://dx.doi.org/10.1021/jp211749g | URI: | http://hdl.handle.net/10261/50875 | DOI: | 10.1021/jp211749g | Identificadores: | doi: 10.1021/jp211749g issn: 1932-7447 |
