Self-assembled monolayers on Pt(111): molecular packing structure and strain effects observed by scanning tunneling microscopy.
Self-assembled monolayers (SAMs) of octanethiol and benzeneethanethiol were deposited on clean Pt(111) surfaces in ultrahigh vacuum (UHV). Highly resolved images of these SAMs produced by an in situ scanning tunneling microscope (STM) showed that both systems organize into a super-structure mosaic of domains of locally ordered, closely packed molecules. Analysis of the STM images indicated a (s...
متن کامل-functionalized self-assembled monolayers chemisorbed on ultraflat Au(111) surfaces for biological scanning probe microscopy in aqueous buffers
Two immobilization procedures for ultimately carrying out scanning probe microscopy of native biological macromolecules in buffer solution are presented. They are based on the preparation of ultraflat template-stripped gold surfaces and subsequent chemisorption of bioreactive -functionalized self-assembled monolayers. Immobilization was achieved either via amide bond formation or diazo linkage....
متن کاملSurface reconstruction transition of metals induced by molecular adsorption
Two surface reconstruction patterns, strikingly different from the Au(111) intrinsic herringbone reconstruction, have been observed at the interfaces between Au(111) and the self-assembled monolayer of perylene or iron phthalocyanine by scanning tunneling microscopy (STM). These interfacial structures, elucidated by using the two-dimensional Frenkel-Kontorova model and density-functional theory...
متن کاملNanoscale observation of dissociative adsorption during self-assembly processes of dialkyl disulfides on Au(111)
The formation of striped phases of dialkyl disulfides on Au(111) and graphite has been monitored by scanning tunneling microscopy (STM). STM imaging clearly exhibits the formation of striped phases having corrugation periodicities that are nearly consistent with the molecular length of alkanethiolate moieties formed after the S-S bond cleavage of dialkyl disulfide on a gold surface. This is the...
متن کاملSelf-assembly of insoluble porphyrins on Au(111) under aqueous electrochemical control.
Self-assembled monolayers of a water-insoluble porphyrin, tetraphenyl porphyrin (TPP), in the presence of an aqueous electrolyte were characterized in situ with electrochemical scanning tunneling microscopy (EC-STM) at working electrode potentials of between 0.5 and -0.2 V. Isolated domains of TPP monolayers with differing orientation were observed on Au(111) in 0.1 M HClO(4) over this entire p...
