The structures of monolayers on Si (100) made up of two acetyl-protected triol ligands, derived from 2-hydroxymethyl-propane-1, 3-diol, namely, RC (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 …
