General description

Biphenyl-4-thiol(BPT) is an alkylthiol that forms a self-assembled monolayer(SAM) which can be used as a spacer chain that enhances the adhesion and frictional forces on a variety of surfaces.

Application

BPT may also be used as a resist in electron lithography to form lubricants for microelectromechanical systems(MEMS). BPT may be used to surface modify gold(Au) which can be potentially used in the formation of freestanding nanosheets.
This material is used to create close-packed monolayers in large-area molecular junctions.† It also finds use as a negative resist material for nanolithography.†
