RT Journal Article T1 Charge-Transfer-Induced Isomerization of DCNQI on Cu(100) A1 Urban, Christian A1 Wang, Yang A1 Rodríguez Fernáncdez, Jonathan A1 Herranz, M.Angeles A1 Alcamí, Manuel A1 Martín, Nazario A1 Martín, Fernando A1 Gallego, José M. A1 Otero, Roberto A1 Miranda, Rodolfo AB This article reports on the temperature-controlled irreversible transition between the two isomeric forms of the strong electron acceptor dicyano-pquinonediimine (DCNQI) on the Cu(100) surface. A combination of experiment (time-resolved, variable-temperature scanning tunneling microscopy, STM) and theory (density functional theory, DFT) shows that the isomerization barrier is lower than in the gas phase or solution due to the fact that charge transfer from the substrate modifies the bond configuration of the molecule, aromatizing the quinoid ring of DCNQI and enabling a more free rotation of the cyano groups with respect to the molecular axis.
