In addition to dative anchor groups, covalent anchors have been reported to yield stable and highly conductive molecular junctions . However, direct formation of Au-C covalent bonds in molecular junctions is challenging and typically requires cleavage or reaction of functional groups such as iodine , alkyne , or diazonium to generate Au-C bonds through in situ reactions. Recently, oriented external electric fields have gained increasing attention for their ability to reorganize the electron distribution of molecules, stabilize charge-separated resonant forms, and promote non-redox reactions .This prior work suggests that it may be possible to form dynamic anchors in nanoscale junctions under external electric fields without the need for cleavage of functional groups, which could provide a new molecular junction binding mechanism for single molecule electronics. However, the structural and electronic properties that promote the formation of Au-C contacts under external electric fields are not yet fully understood.
