Application
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
