Reusable surface confined semi-conducting metal-TCNQ and metal-TCNQF4 catalysts for electron transfer reactions

Magneto-controlled Quantized Electron Transfer to Surface-confined Redox Units and Metal Nanoparticles

Hydrophobic magnetic nanoparticles (NPs) consisting of undecanoate-capped magnetite (Fe3O4, average diameter ca. 5 nm) are used to control quantized electron transfer to surface-confined redox units and metal NPs. A two-phase system consisting of an aqueous electrolyte solution and a toluene phase that includes the suspended undecanoatecapped magnetic NPs is used to control the interfacial prop...

Light Induced Electron Transfer Reactions of Metal Complexes

Properties of the excited states of tris(2,2'—bipyridine) and tris(l,lO—phenanthroline) complexes of chromium(III), iron(II), ruthenium(II), osmium(II), rhodium(III), and iridium(III) are described. The electron transfer reactions of the ground and excited states are discussed and interpreted in terms of the driving force for the reaction and the distortions of the excited states relative to th...

Controlling the electron transfer mechanism in metal–molecules–metal junctions

We show how the mechanism of electron transfer through molecules can be switched between different regimes by using Hg-based metal–molecules–metal junctions. The junctions are easy to assemble and allow for hosting of self-assembled monolayers (SAMs) of a large variety of molecular structures. In this paper, we compare results from studies of charge transport across two different types of junct...

Technique Prints Metal Films with Reusable Stamps and Tailored Surface

584 MRS BULLETIN/AUGUST 2002 Nanoscale Technique Prints Metal Films with Reusable Stamps and Tailored Surface Chemistry Traditional nanolithographic techniques such as electron-beam or deep-UV nanolithography are limited to patterning small regions of specialized materials on rigid, ultraflat inorganic substrates. These restrictions are unacceptable for nascent applications in fields such as pl...
