Formation of interchain carboxylic anhydrides on self-assembled monolayers with Fluoro N,N,N′,N′-tetramethylforamidinium hexafluorophosphate.1 This compound is used in self-assembly to produce hydrophilic SAMs. The resulting monolayers which are terminated with carboxylic acids can be further functionalized2 with various amines and alcohols to introduce more complex end groups or multiple layers.3
MHA forms a SAM on gold surfaces by pen lithography (PPL). It finds potential application in bio-engineering. It can also be used to functionalize gold-dypiramids, which can fabricate nano-resonators for shell-isolated nanoparticle enhanced Raman-spectroscopy (SHINERS).
16-Mercaptohexadecanoic acid (MHA) is an alkanethiol with long chained CH2 groups, which form a self-assembled monolayer (SAM) on a wide range of substrates.
