1-Dodecanethiol (NDM)is an organosulfur compound. It has a 12-carbon alkyl chain attached to a thiol (-SH) group. A colorless liquid with a characteristic sulfur odor, it is sparingly soluble in water but soluble in organic solvents. It's chemically reactive, often used in surface modification, as a chain transfer agent in polymerization, and for its role in forming self-assembled monolayers.

Surface Modification and Self - Assembled Monolayers (SAMs)
1 - Dodecanethiol is widely used for surface modification, especially in the formation of self - assembled monolayers. When it is in contact with a metal surface such as gold, silver, or copper, the thiol group (-SH) has a high affinity for the metal atoms. The molecules spontaneously assemble into an ordered monolayer on the surface. For example, on a gold nanoparticle surface, 1 - dodecanethiol can form a monolayer that changes the surface properties from hydrophilic to hydrophobic. This is crucial in many applications such as in the development of biosensors, where the modified surface can selectively interact with target biomolecules.
Polymer Chemistry
In polymer synthesis, 1 - dodecanethiol serves as a chain - transfer agent. In radical polymerization reactions like the polymerization of styrene or acrylate monomers, it controls the molecular weight of the resulting polymers. The thiol group can react with the growing polymer radical chain, terminating its growth and transferring the radical to a new monomer molecule. This allows for the production of polymers with more controlled molecular weights and narrower molecular weight distributions.
Lubrication and Tribology
The long alkyl chain of 1 - dodecanethiol provides lubricating properties. It can be used as an additive in lubricants. When added to oils or greases, it forms a thin film on the surface of moving parts. The thiol - metal interaction helps in adhering the film to the metal surfaces, reducing friction and wear. This is beneficial in various mechanical systems such as engines and industrial machinery to improve their efficiency and lifespan.
Ink and Coating Formulations
In the formulation of inks and coatings, 1 - dodecanethiol can be used to modify the surface tension and wetting properties. The hydrophobic nature of the alkyl chain helps in improving the spreading and leveling of the ink or coating on different substrates. It can also enhance the adhesion of the coating to the substrate, especially in cases where a hydrophobic surface is desired, such as in some outdoor coatings or in the printing of non - porous materials.
