Aromatic self-assembled monolayers to surface metal complexes: electrochemistry and XPS insights of interfacial structure

Year: 2026

Type: article

Abstract: sputtering, with the C 1s depletion time increasing from 95 s for pristine BPD to 245 s for crosslinked BPD and 195 s for BPD-Ni, corresponding to 2.6-fold and 2.1-fold enhancements, respectively. The combined electrochemical and XPS results demonstrate that crosslinking and metal coordination improve SAM's robustness through the formation of interconnected molecular networks rather than increased molecular packing. These findings provide an effective strategy for developing robust bipyridine-based SAMs for molecular electronics, electrocatalysis, and sensing applications.
