Infrared Reflection-Absorption Study of Ordering and Hydrogen Bonding within Chiral and Nonchiral Self-Assembled Monolayers on Gold
Abstract:Ordering processes in chiral and racemic monolayers of three phenylalanyl-substituted omega-thiol alkanoic acids on gold have been investigated with the use of infrared reflection absorption spectroscopy. For chiral molecules, packing is influenced by both hydrogen-bonding interactions between the end groups at the air/monolayer interface and the length of the spacer chain within the monolayer. Results for a mixed monolayer of octadecylmercaptane and phenylalanyl-substituted omega-thiol docosanoic acid indicate that formation of large islands of either one of the compounds can be excluded. For a racemic monolayer of phenylalanyl-substituted omega-thiol undecanoic acid, a dense, yet unregular, packing is observed.
