The preparation and characterization of self-assembled organic monolayers is reviewed, using examples from covalently attached monolayers (organothiols on gold) and noncovalently bound assemblies (hydrocarbons on graphite). Odd or even effects on the properties of these monolayers, as well as the ...
Self-assembled monolayers and patterning by μCP illustrate a largely unexplored approach to microfabrication. Microcontact printing is attractive because it is simple, straightforward, inexpensive, and flexible. The elastomeric PDMS stamp and the surface chemistry for the formation of SAMs can also be ...
Self-assembled monolayers of dithiols, diisocyanides, and isocyanothiols on gold ‘chemically sticky’ surfaces for covalent attachment of metal clusters and studies of interfacial electron transfer 文档格式: .pdf 文档大小: 1.1M 文档页数: 10页 ...
Direct, Noncovalent Coating of a Gold Surface with Polymeric Self-Assembled Monolayers 来自 学术范 喜欢 0 阅读量: 15 作者:H Lee,D Hong,S Jon,IS Choi 摘要: We demonstrated a simple but rather unexpected method for coating a gold surface with the random copolymer presenting a long alkyl chain...
Here we report a route to crystal formation, using micropatterned self-assembled monolayers17,18, which affords control over all these parameters. We begin with a metal substrate patterned with a self-assembled monolayer having areas of different nucleating activity—in this case, an array of acid...
To transfer these bulk structural properties to thin films, self-assembled monolayers (SAMs) were obtained by adsorption from solution and characterized by water contact angle measurements, null ellipsometry, and atomic force microscopy (AFM). Employing the concentration as an additional degree of f.....
Self-Assembled Monolayers Self-assembled monolayers (SAMs) are formed by absorption of alkanethiols, typically onto a gold surface. Alkanethiols that terminate in short PEG groups provide improved nonspecific absorption properties. Functional and nonfunctional polymers are usually mixed to optimize the den...
Self-assembled monolayers (SAM) of Schiff base N,N'-ophenylen-bis(3-methoxysalicylaldenimine), designated as V-o-Ph-V and N-2-hydroxyphenyl-(3-methoxysalicylidenimine), designated as V-bso, were formed on a copper surface pretreated using different methods. The process of self-assembly wa...
This article introduces the concepts of molecular ordered films including LB films, self-assembled monolayers, and molecular deposition films and their characterizations of structure, thickness,property and microtribology. 介绍了LB膜、自组装单分子膜(SAMs)、分子沉积(MD)膜等分子有序膜的基本概念和薄膜结...
Determination of the surface pK_a of self-assembled monolayers (SAMs) at aqueous buffer/gold interfaces, and the shift of pK_a values with the change of electrode potentials by direct observation of counter anion by Fourier transform-surface enhanced Raman scattering (FT-SERS) measurements, namely...
