Friction measurements on phase-separated thin films with a modified atomic force microscope

Abstract: THE study of chemical phase separation in multicomponent thin organic films typically involves the addition of a dye which is selectively more soluble in one of the phases, thereby making it possible to probe the domain structures by fluorescence microscopy1–4. The resolution of this approach is generally limited to tens of micrometres. The atomic force microscope, on the other hand, has recently proved useful for imaging organic thin films down to the atomic scale5–9, but this technique provides details of the overall film topography, rather than the chemical composition. Here we show that the recently developed friction force microscope10–13, which simultaneously measures both the normal and lateral forces on the scanning tip, can be used to image and identify compositional domains with a resolution of ∼5 A. Although the topography of the individual domains can be imaged with a standard atomic force microscope, it is the additional information provided by the friction measurement that allows them to be chemically differentiated.

Ionic recognition and selective response in self assembling monolayer membranes on electrodes

Abstract: According to the invention organic monolayer films are applied to an electrically conductive substrate, resulting in an electrode which can be used in electrochemical processes. The said film serves as ultrathin membrane and allows certain selected species to approach the substrate and be detected. The film comprises active species which are selective towards specific species contained in mixture with others and a blocking surface sealing component. It is also possible to use one compound serving both purposes. The components of the film are attached to the substrate by a variety of means: adsorption, chemisorption, electro-chemical deposition.

Single electron transfer and nucleophilic substitution

Abstract: Publisher Summary This chapter discusses single electron transfer and nucleophilic substitution. The SRNl reaction appears as a reaction in which single electron transfer plays a pre-eminent role but is by no means a single elementary step. A different problem is that of the possible involvement of single electron transfer in reactions that are not catalyzed by electron injection (or removal). A typical example of such processes is another substitution reaction—namely, the SN2 reaction. The chapter discusses the reactions in which electron transfer is associated with the breaking of a bond but in which either no bond formation occurs or, if it does, it takes place in aseparated step. There are a number of cases where “true” SN2 mechanisms (in which the bond-breaking and bond-formation steps are concerted) do occur, even with nucleophiles that are members of reversible one-electron reversible redox couples.
