Journal ArticleDOI
Conductance of a single conjugated polymer as a continuous function of its length
TL;DR: This work measures the conductance and mechanical characteristics of a single polyfluorene wire by pulling it up from a Au(111) surface with the tip of a scanning tunneling microscope, thus continuously changing its length up to more than 20 nanometers.
Journal ArticleDOI
Voltage-dependent conductance of a single graphene nanoribbon
TL;DR: It is shown that the conductance properties of a single molecule can be correlated with its electronic states and the importance of the edge states and a planar geometry.
Journal ArticleDOI
Controlled clockwise and anticlockwise rotational switching of a molecular motor
U.G.E. Perera,Francisco Ample,Heath Kersell,Yuan Zhang,Guillaume Vives,Jorge Echeverría,Maricarmen Grisolia,Gwénaël Rapenne,Christian Joachim,Saw-Wai Hla +9 more
TL;DR: It is shown that a stand-alone molecular motor adsorbed on a gold surface can be made to rotate in a clockwise or anticlockwise direction by selective inelastic electron tunnelling through different subunits of the motor.
Journal ArticleDOI
Adsorption and Switching Properties of Azobenzene Derivatives on Different Noble Metal Surfaces: Au(111), Cu(111), and Au(100)
Micol Alemani,Sofia Selvanathan,Francisco Ample,Maike V. Peters,K. H. Rieder,Francesca Moresco,Christian Joachim,Stefan Hecht,Leonhard Grill +8 more
TL;DR: In this article, the adsorption and switching behavior of 3,3′,5,5′-tetra-tert-butylazobenzene (meta-TBA) were investigated by low-temperature scanning tunneling microscopy on three different metal substrates: Au(111), Cu(111, and Au(100).
Journal ArticleDOI
Step-by-step rotation of a molecule-gear mounted on an atomic-scale axis.
Carlos Manzano,We-Hyo Soe,Hon Seng Wong,Francisco Ample,André Gourdon,N. Chandrasekhar,Christian Joachim +6 more
TL;DR: The mechanics of an intentionally constructed molecule-gear on a Au(111) surface are presented, mounting and centring one hexa-t-butyl-pyrimidopentaphenylbenzene molecule on one atom axis, leading to the construction of a fundamental component of a planar single-molecule mechanical machine.
