Effects of mechanical compression on the vibrational spectrum of a self-assembled monolayer

Aminothiophenol Furfural Self-assembled Gold Electrode Sensor for Determination of Dopamine in Pharmaceutical Formulations

A new Schiff base 2-aminothiophenol furfural self assembled monolayer (SAM) has been fabricated on a bare gold electrode as a novel sensor for determination of dopamine. Electrochemical impedance spectroscopywas utilized to investigate the properties of the Au 2-aminothiophenol furfural self assembled monolayermodified electrode (Au ATF SAM-ME) using the [Fe(CN)6]3-/4- redox couple. The electro...

Synthesis of Two Compounds with Self-Assembled Monolayer Properties: Riboflavin 2', 3', 4' , 5' Tetra Octadecanoate & Bis (Phosphatidyl Ethanol) Protoporphyrin IX Amide

Riboflavin and protoporphyrin IX are two molecules that participate in oxidation and reduction reactions in the living cell. Changing some functional groups of riboflavin and protoporphyrin IX can provide compounds with self-assembled monolayer properties with wide applications in designing the molecular electronic devices. In this study, the amphiphilic structure of riboflavin and protopor...

Probing the Molecular Conformation of Self-Assembled Monolayers at Metal/Semiconductor Interfaces by Vibrational Sum Frequency Generation Spectroscopy

Indentation and self-healing mechanisms of a self-assembled monolayer--a combined experimental and modeling study.

A combination of in situ vibrational sum-frequency generation (SFG) spectroscopy and molecular-dynamics (MD) simulations has allowed us to study the effects of indentation of self-assembled octadecylphosphonic acid (ODPA) monolayers on α-Al2O3(0001). Stress-induced changes in the vibrational signatures of C-H stretching vibrations in SFG spectra and the results of MD simulations provide clear e...

Compression-Induced Structural Transition in a Self-Assembled Monolayer

Molecular dynamics simulations are used to probe the atomic-scale behavior of a model for a selfassembled monolayer of n-hexadecanethiol chemisorbed on a gold (111) surface compressed under high loads. These simulations suggest that SAMs may undergo abrupt rearrangements during compression that retain efficient packings of the chains. These changes may in turn modify the elastic properties of t...
