Fluorinated self-assembled monolayers: composition, structure and interfacial properties

Inverted Surface Dipoles in Fluorinated Self-Assembled Monolayers

The presence of surface dipoles in selfassembled monolayers (SAMs) gives rise to profound effects on the interfacial properties of the films. For example, CF3terminated alkanethiolate films are surprisingly more wettable toward polar contacting liquids than analogous hydrocarbon SAMs due to the fluorocarbon-to-hydrocarbon transition (CF3−CH2) at the interface (i.e., the presence of a strong “FC...

Study on the barrier properties and interfacial properties of self-assembled monolayers (SAMs) of aliphatic, aromatic and alkoxycyanobiphenyl thiols on gold surface prepared using a lyotropic liquid crystalline phase as an adsorbing medium

First-principles study on the electronic structure of Thiophenbithiol (TBT) on Au(100) surface

First principle calculations were performed using Density functional theory within the local spin density approximation (LSDA) to understand the electronic properties of Au(100)+TBT system and compare the results with Au(100) and bulk Au properties. Band structure, the total DOS and charge density for these materials are calculated. We found that the HOMO for Au(100)+TBT becomes broader than Au...

Rapid evaluation and screening of interfacial reactions on self-assembled monolayers.

This paper reports 16 chemical reactions for elaborating the structures of self-assembled monolayers (SAMs) of alkanethiolates on gold. This work takes advantage of matrix-assisted laser desorption/ionization and time-of-flight mass spectrometry (MALDI-TOF MS) to rapidly characterize the products and yields of reactions that occur with molecules attached to monolayers. The paper also describes ...
