Fibrillar self-organization of a line-active partially fluorinated thiol within binary self-assembled monolayers.
Self-assembled monolayers (SAMs) were prepared from a novel two-tailed partially fluorinated thiol (F8C11/C16), possessing one hydrocarbon chain and one chain with an extended fluorinated segment, and from mixtures of F8C11/C16 and hexadecanethiol (C16) on gold, with the expectation that the internal chemical dissimilarity and wedge-like shape of F8C11/C16 would lead to unique self-organization...
متن کاملModification of Copper with Self-assembled Thiol Monolayers
Self-assembled monolayers (SAM) make the creation of new types of protective layers possible, concerning corrosion, with which ecologically damaged procedures would be replaced for the protection of metal constructions from corrosion. Self-assembling is a spontaneous process which is developed by submerging of suitable metal substract into the melt with surface organic active substance, which i...
متن کاملFormation and Structure of Self-Assembled Monolayers.
The field of self-assembled monolayers (SAMs) has witnessed tremendous growth in synthetic sophistication and depth of characterization over the past 15 years.1 However, it is interesting to comment on the modest beginning and on important milestones. The field really began much earlier than is now recognized. In 1946 Zisman published the preparation of a monomolecular layer by adsorption (self...
متن کاملNanopattern formation in self-assembled monolayers of thiol-capped Au nanocrystals.
The structure and the stability of the transferred monolayers of gold-thiol nanoparticles, formed at air-water interface at different surface pressure, on to silicon surface have been studied using two complementary techniques, x-ray reflectivity and atomic force microscopy (AFM). Networklike nanopatterns, observed through AFM, of the in-plane aggregated nanoparticles can be attributed to the l...
متن کاملThe Electronic Structure of Mixed Self-Assembled Monolayers
The electronic structure of mixed self-assembled monolayers (SAMs) on Au(111) surfaces is modeled using slab-type density-functional theory calculations. The studied molecules have a dipolar character induced by polar and electron donating or accepting tail-group substituents. The resulting electronic structure of mixed layers is found to differ qualitatively from a simple superposition of thos...
