The miniaturization of electronic devices has driven remarkable advances ranging from portable computing devices to high-speed communication and high-density data storage . In recent years, the transistor density on silicon-based microchips has doubled approximately every two years in accordance with Moore's Law . Although this empirical observation has held true for decades, physical size limitations are beginning to disrupt this trend . Molecular electronics offers a potential path forward for continued miniaturization of nano-and microelectronic devices . Single-molecule junctions generally consist of a molecular bridge linked to two or more metal electrodes via terminal anchor groups (e.g., thiol, amine, or pyridine) . Despite recent progress , achieving robust and controllable conductance in singlemolecule junctions remains challenging due to the dynamic nature of molecular conformations that invariably fluctuate over operational timescales at ambient temperatures, destabilizing device performance and impacting reproducibility. Using standard microfabrication techniques, it is challenging to construct electrodes with sub-5 nm features tailored for specific molecules, which leads to distorted molecular conformations in nanoscale junctions . Uncertainties in nanogap dimensions ultimately lead to unfavorable broad variations in molecular conductance .
