Single-molecule junctions, in which a single molecule bridges a nanogap between two metal electrodes, have attracted significant attention as a fundamental model for ultra-small electronic devices. In particular, molecular junctions with π-delocalized systems exhibit excellent electronic conductivity and have been extensively studied. In contrast, the charge transport properties of molecular junctions with σ-delocalized systems, which possess orbital configurations distinct from those of π-delocalized systems, remain largely unexplored. In this study, we investigated the electronic conductivity of molecules with σ-delocalized systems and compared it with that of π-delocalized systems. Our findings reveal that molecules with σ-delocalized systems exhibit higher electronic conductivity than those with π-delocalized systems.
