    • The initial deposition of the longer thiols is advantageous because they form more stable monolayers on Au and therefore are less perturbed by the anodic desorption of the thiols on the adjacent electrode. This strategy also minimizes the possibility of exchange with the second thiol solution

    • It is preferred that the anodic desorption procedure be performed prior to the attachment of the electroactive species onto the electrode. It was observed that anodic desorption of thiols from electrode 1 leads to decay of ferrocene when it is attached to electrode 2 prior to the desorption step Figure S3 in the Supporting Information, This loss of coverage was also observed when the desorption was carried out in 0.1 MHClO4 or pH 7 buffer containing 0.1 M KPF6. However, this process is less damaging if electrode 1 contains the azide functionality

    • The method described here uses a chemical reductant to form the Cu(I) catalyst for the click reaction. This approach is complementary to the electrochemical activation and deactivation of the coupling catalyst for a selective click reaction on a given electrode (ref 7).
