    • note
    • Insertion into a thicker matrix was attempted, but unsuccessful: we attribute this to steric hindrance where the disulfide bond is unable to access the substrate and thus unable to chemisorb dissociatively.

    • note
    • As a general observation, molecules inserted from the dimerized version of the nitro-functionalized OPE exhibit switching events more frequently than do single molecules. This is likely a consequence of the bias in our experiment; we require relatively larger defects in the matrix to enable access and dissociative chemisorption of the disulfide molecules (vs thiol) to the substrate. We have previously shown that the rigidity of the matrix around the switches determines the frequency of switching.
