Self assembling monolayers
WebFeb 1, 2024 · As general phenomena of self-assembly, SAMs are defined as the formation of monolayers by self-assembly of surfactant molecules at surfaces.40,41 The molecules for SAMs typically consist of an anchoring group (or headgroup), a linkage, and a functional group (or terminal group). The anchoring groups are designed to fasten the molecules … WebLecture 3: Self-assembled Monolayers (SAMs) Chain tilting in SAMs of thiolates on Au(111) 26-28° from the surfacefrom the surface normal (or 11-14°) This tilt is a result of the chains reestablishing VDW contact in an assembly with 5 Å S S distance, Self-assembly and Nanotechnology Abraham Ulman, Chem.
