Seeing both sides
To improve organic electronic devices, the principles underlying organic-film/metal-electrode interfaces must be understood. A comprehensive study of the organic electron acceptor TCNQ on a copper surface reveals a structural rearrangement of both the organic molecule and the metal surface atoms after charge transfer across the interface.

Exploring local currents in molecular junctions
A methodology for describing local electronic transmission through bridging molecules between metallic electrodes is presented. Its application to simple alkane, phenyl and cross-conjugated systems highlights an unexpected number of cases whereby ‘through space’, rather than ‘through bond’ terms dominate and that interference effects coincide with the reversal of ring currents.
