  text: Probing structural changes of a molecule induced by charge transfer is important
    for understanding the physicochemical properties of molecules and developing new
    electronic devices. Here, we interrogate the structural changes of a single diketopyrrolopyrrole
    (DPP) molecule induced by charge transport at a high bias using scanning tunneling
    microscope break junction (STM-BJ) techniques. Specifically, we demonstrate that
    application of a high bias increases the average nonresonant conductance of single
    Au–DPP–Au junctions. We infer from the increased conductance that resonant charge
    transport induces planarization of the molecular backbone. We further show that
    this conformational planarization is assisted by thermally activated junction
    reorganization. The planarization only occurs under specific electronic conditions,
    which we rationalize by ab initio calculations. These results emphasize the need
    for a comprehensive view of single-molecule junctions which includes both the
    electronic properties and structure of the molecules and the electrodes when designing
    electrically driven single-molecule motors.
