Download or read book Self-Assembled Monolayers on Gold Substrates written by Mihaela Georgeta Badin and published by VDM Publishing. This book was released on 2008 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembled monolayers (SAMs) consist of densely packed long-chain organic molecules, which are chemisorbed on metal substrates through a sulfur head group. The purpose of this work, is to study the arrangement and structure of SAMs by IR, XPS, NEXAFS, STM, Ellipsometry and contact angle. While the first group of triptycenethiols and the second group of triarylaminethiols show a formation of disordered films on the gold surface, the third group of alkanethioacetates shows the formation of highly ordered monolayers. A further adsorption to upright oriented molecules is hindered due to kinetic effects. In the case of azo-molecules it is shown that the photoisomerization process is not reversible. These molecules are not able to form highly ordered monolayers on the gold surface due to the critical effect of azo-moiety.

This book was released on 2007 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low energy (tens of eV) polyatomic cations were used as probes for characterization of monolayers of spontaneously chemisorbed thiols on gold. Characteristics including chemical composition, surface order and orientation of the self-assembled monolayers (SAMs) can be derived by monitoring the products of projectile ion neutralization, surface-induced dissociation (SID), and ion-surface reactions. To study the influence of the terminal group chemical structures and orientations of the SAMs on ion-surface interactions, a series of semi-fluorinated alkane thiols with difluoromethylenes buried underneath hydrocarbon terminal groups were examined (CH3CF2CH2− and CH3CH2CF2−). Compared to terminally fluorinated SAMs, they showed more projectile ion neutralization and less internal to vibrational energy deposition into precursor ions. Projectile ion-hydrocarbon reactions decreased significantly when difluoromethylenes are one or two bonds away from the terminal group. Furthermore, ion-surface reaction results on surfaces with odd and even chain lengths suggested that they have similar terminal methyl orientations to their hydrocarbon counterparts. Mixed monolayers of CF3CF2(CH2)14SH (F-SAMs) and CH3(CH2)15SH (H-SAMs) with systematically changing electron transfer, energy deposition and ion-surface reaction were prepared using mixed thiols solution and micro-contact printing (μ-CP). The solution mixture system showed linear variations in electron transfer and energy deposition with different F-SAM surface concentrations, while non-linear changes occur for ion-surface reaction suggesting strong lateral interactions between the two components. These interactions are minimized in theμ-CP system containing domains of each thiol. Energy deposition on the patterned surfaces varies non-linearly with changing F-SAM concentration which differs from the homogenously mixed system. To explore SID with a 90 collision angle, eV SID of a series of protonated peptide ions were performed in an in-line sector Time-Of-Flight (TOF) mass spectrometer. The results were compared to keV collision-induced dissociation (CID) data collected with the same instrument. Fragmentation efficiency for SID was higher than CID for those peptides. In addition to the excellent control over laboratory collision energies with SID, different amount of energy deposition can be achieved when varying surface composition, e.g. using mixed F-SAM/H-SAM. Reactive ion scattering spectrometry (RISS) results provided more in-depth knowledge of low energy ion-surface interactions that will promote usage of RISS as a novel surface characterization technique.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of thin films is critical to the understanding of many technological and biological processes. The focus of this dissertation is to develop methods to characterize very low concentration species present on surfaces. A reflection adsorption infrared spectroscopy (RAIRS) system was constructed and tested. The instrument comprises an Fourier transform infrared (FTIR) spectrometer, an optical pathway and a vacuum chamber. The RAIRS system is designed to investigate in situ the interaction of vapor-deposited metals and gases, such as CVD precursors, with organic thin films, and so a vacuum chamber is required. To accommodate the vacuum chamber, an external IR optical pathway was designed and assembled because there was not enough room in the internal optical pathway of the FTIR spectrometer. The synthesis and characterization of terminal alkyne monolayers (TAMs) adsorbed on gold was investigated by RAIRS, single wavelength ellipsometry, time-of-flight secondary ion mass spectrometry (TOF SIMS) and x-ray photoelectron spectroscopy (XPS). TAMs have the potential to transform surface functionalization for many technological applications because they have increased temperature stability and electrical conductance. However, the data suggest that TAMs are not well-ordered and can be oxidized, which may limit their application. For TAMs with less than 11 methylene units in the backbone, the adsorbed layer is highly disordered, oxidized and has a multilayer structure. Longer chain length TAMs form disordered monolayers on gold. As the methylene chain length increases, the conformational order of the TAMs increases with the alkynes in an upright conformation and bound to the surface via a Au-C[identical to]C- bond. The use of room temperature ionic liquids (ILs) as matrices in TOF SIMS was examined to further characterize biological thin films. The data indicate that the secondary ion intensities of lipids, steroids, peptides, proteins and proteins are significantly enhanced using IL matrices. Secondary ion enhancements of at least an order of magnitude are typically observed. Limits of detection are also greatly improved. For example, the limits of detection of 1,2-dipalmityl-sn-glycero-phosphocholine (DPPC) and 1,2-dipalmityl-sn-glycero-phosphoethanolamine (DPPE) were at least two orders of magnitude better. The data also show that ILs are suitable matrices for imaging SIMS. The IL matrices did not cause changes to the sample surface; no "hot spots" were observed. The mechanism of the secondary ion intensity enhancements using IL matrices was then investigated to optimize use in characterization. Only protic ILs, which are formed by the transfer of a proton from a Brønsted acid to base, were observed to increase analyte signals. The matrix enhancement mechanism therefore involves the transfer of protons from, or to, the analyte, to, or from the matrix. The magnitude of the analyte signal enhancements is dependent on the chemistry of the matrix cation, anion and analyte. The pKa of the matrix acid and base do not appear to have a strong effect on the ion-intensity enhancements. The results also indicate that the chemical identity of the matrix anion has a stronger effect on analyte signal enhancements than the matrix cation

Book excerpt: The focus of the book is the modification of surfaces to tailor them for a specific purpose. Using this method of surface modification, materials chosen for their bulk properties (tensile strength, temperature stability, density, price can be optimized for any particular application, which can lead to improved hardness, biological inertness or activity, corrosion resistance, low or high friction or adhesion, water repellency or wettability, or catalytic activity. The works of the author — many of his crucial papers are included — touches upon these surface properties and spans fields including catalysis, analytical surface science, self-assembled monolayers, tribology, biomaterials, superhydrophobicity and polymer coatings.
