General description

m-Carborane-1-thiol (M1) is a boron cluster compound that is also known as icosahedral carborane thiol. It forms a self-assembled monolayer (SAM) by attaching the thiol groups with surface atoms. This SAM forms a two dimensional matrix on the metal surface that enables the tuning of surface properties such as a work function, and wettability.

Application

M1 forms a mixed SAM with m-carborane-9-thiol (M9), which is used to tune the work function of gold and silver surfaces for the fabrication of organic light emitting diodes (OLEDs).
