General description

1-Hexadecanethiol (HDT) readily forms self-assembled monolayer (SAMs) on gold surfaces. Phase separation characteristics of binary SAMs [made up of HDT and 3-mercaptopropionic acid] on the surface of Au(111) have been investigated. Interaction between gold surface and SAM of HDT has been investigated by atomic force microscopy (AFM).

Application

1-Hexadecanethiol has been used in the preparation of cholesterol-PIE12-trimer and alkyl-PIE12-trimer (PIE12-trimer = protease-resistant trimeric D-peptide inhibitor). It may be used for the functionalization of silver nanowires.

An atomic force microscope (AFM) was used to measure the forces between gold surfaces with and without hydrophobizing them by the self-assembly of 1-hexadecanethiol. The forces measured between bare gold surfaces were fitted to the Derjaguin-Landau-Verwey-Overbeek (DLVO) theory with a
