In single-molecule transistors (SMTs), understanding the relationship between molecular structure and electron transport mechanisms is crucial. In this study, we synthesized Si2x2 derivatives with biphenyl groups and ethinylphenyl groups—which inhibit twisting and help maintain π-conjugation—as linker groups. We fabricated SMTs by chemically adsorbing these rigid-backbone molecules onto Au/Pt nanogap electrodes prepared through electroless gold plating (ELGP). We examine how different linker structures influence SMT properties and intramolecular π-conjugation.
