Influence of Terminal Carboxyl Groups on the Structure and Reactivity of Functionalized m-Carboranethiolate Self-Assembled Monolayers

2 B 10 H 10 and racem-1-COOH-7-SH-1,7-B 10 H 10 and racem-1-COOH-9-SH-1,7-C 2 B 10 H 10 & B 10 H 10 are characterized, and their SAMs on Au111 are determined. The second example, which was to our knowledge, was the first example assembled on Au111. The thiol group bonded to either carbon or boron atoms, according to analyses of the functional groups' influence by the pseudo-aromatic m-carborane skeleton, raises the carboxyl group acidity in solution. The acidity of the exposed carboxyl group in the SAMs decreases on surface attachment, according to computer studies; the driving force of this change is the dielectric of the atmosphere in the monolayer as a result of restricted intermolecular interactions, nearness to the Au surface, and partial desolation.
