詳細
1-Octadecanethiol (ODT) is a water soluble sulfur compound with an 18 carbon alkyl chain, which forms a strong hydrophobic assembly with transition metals, like gold .It forms self-assembled monolayers (SAMs) on the surface of such transition metals. The thiol membrane when covalently bonded with the surface of the metal electrode, it shows electrostriction phenomenon leading to variation in capacitance.ODT SAMs have a hydrophobic surface with contact angle of 102oC.
アプリケーション
ODT is used to deposit thiolated molecules onto the surface of gold substrates, such as
- SAMs on gold quartz crystal resonators.
- on the tip of atomic force microscope probes.
- capacitive sensors.

Three types of thiol compounds (n-octadecanethiol, thiophenol, and 2-phenylethanethiol) were used to modify the gold-coated polystyrene particles (dp. 5microm) to prepare a stationary phase for capillary liquid chromatography through the formation of self-assembled monolayer. The column with n-octadecanethiol-modified gold-coated polystyrene
