Self-Assembled Monolayers Containing oMercaptoalkylboronic Acids Adsorbed onto Gold Form a Highly Cross-Link€d, Thermally Stable Borate Glass Sur{acer

Introduction This paper describes studies of the preparation and characterization of self-assembled monolayers (SAMs) formed by the adsorption of an @-mercaptoalkylboronic acid, 1l-mercaptoundecanyl-l-boronic acid, 1, onto a gold substrate. This work is part of a program to study the physicalorganic chemistry of organic interfaces.2 SAMs of alkanethiolates on gold are particularly useful substrates for studying organic surface chemistry because the high affinity of sulfur for gold3-6 allows the incorporation of a wide range of tail groups, X, into precursor alkanethiols ofthe general formula HS(CH2)"X.7-15 SAMs of alkanethiolates on gold are useful model systems in fundamental studies of electrochemistry,lG protein ad-
