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.

The c(4 x 2) structure of C16H33SH alkanethiol monolayers self-assembled on Au(111) has been studied by grazing incidence X-ray diffraction. This structure coexists on the surface with the (radical3x radical3)R30 degrees phase. The structural refinement of the c(4 x 2)

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

The highly conserved HIV-1 gp41 "pocket" region is a promising target for inhibiting viral entry. PIE12-trimer is a protease-resistant trimeric d-peptide inhibitor that binds to this pocket and potently blocks HIV entry. PIE12-trimer also possesses a reserve of binding energy
