I will report on recent experiments on single-molecule junctions. Using the mechanically controlled break junction technique and metallic electrodes, we found evidence that vibrations have a remarkably strong temperature-dependent effect on the charge transport [1]. In a second line of experiments, we read out the magnetic state of individual molecules [2], which can be switched under finite bias. Finally, I will present ongoing experiments using graphene nanoelectrodes that permit significantly refined experimental control.
