1-Dodecanethiol

1-Dodecanethiol (DDT) is a premier alkanethiol for depositing highly ordered, hydrophobic Self-Assembled Monolayers (SAMs) on gold and noble metals. This ≥98% purity grade ensures crystalline-like molecular packing with minimal surface defects, critical for single-molecule electronics. As the gold standard for nanoparticle stabilization, its C12 chain offers the optimal balance between dense van der Waals packing and liquid-phase solubility, providing superior ease of handling compared to longer-chain analogs.

As a versatile molecular bridge, DDT is essential for engineering intelligent interfaces and stimuli-responsive systems that enable precise interactions at the intersection of nanotechnology, biology, and electronics.


• Nanoparticle Capping: Provides a robust hydrophobic shell for Gold, CdS, and PbS nanocrystals, preventing aggregation and enabling solvent-phase processing.


• Steric Spacing: Acts as a critical "diluent" in mixed SAMs to precisely tune the lateral density of bulky bioreceptors (DNA/proteins), optimizing binding kinetics in biosensors.


• Molecular Electronics: Serves as a foundational dielectric spacer in molecular junctions to study electron tunneling across individual organic molecules.


• Quantum Dot Synthesis: Functions as a stable sulfur source for the solvothermal growth of magic-sized nanocrystals used in bio-imaging and optoelectronics.


• Interface Protection: Forms a non-conductive, anti-corrosive barrier on copper and germanium surfaces for futuristic microelectronics and medical implants.
