XPS, FTIR-ATR, and AFM Structural Study of Silicon-Grafted Triol Monolayers for Controlled Anchoring of Single Molecule Magnets

Abstract: The structures of monolayers on Si(100) made up of two acetyl-protected triol ligands, derived from 2-hydroxymethyl-propane-1,3-diol, namely, R-C(CH2OAc)3 with R = CH2CH−(CH2)9−O−CH2− and R = CH2CH−(CH2)7−, have been investigated. After deprotection, the two ligands are well-suited receptors for anchoring molecular functionalities, such as Fe4 single molecule magnets, to the Si surface through OH groups. Monolayers were obtained by the hydrosilylation reactions between H-terminated Si(100) and the CH2CH− en… Show more

“…a chemical reaction between the surface and the adsorbed molecules with formation of new chemical bonds. The introduction of thioacetyl or 1,2‐dithiolane groups in the structure of Fe 4 systems triggers the chemisorption of these molecules on gold surfaces;, , similarly, alkene groups can be added to drive chemisorption on H‐terminated silicon surfaces , , . Here, the formation of a chemical bond with the surface limits selectively to one layer the thickness of the molecular deposit.…”
