We present a reliable, label-free single-molecule approach that allows us to directly explore the dynamic process of basic chemical reactions at the single-event level by using stable graphene-molecule single-molecule junctions.  These junctions are constructed by covalently connecting a single molecule with a 9-fluorenone center to nanogapped graphene electrodes.
