Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...
One of the major challenges faced by organic chemistry is the efficient synthesis of increasingly complex molecules. Since October 2007, the Laboratory of Catalysis and Organic Synthesis (LCSO) at EPFL has been working on the development of catalytic react ...
This thesis is primarily concerned with optical properties of adsorbed C60 molecules on metal and insulating substrates. These properties were studied on a single-molecule scale, using Scanning Tunneling Microscope-induced light emission spectroscopy (STM- ...
Some redox-active ionic liquids, organic amorphous solids containing electron-donating moieties, and conductive polymers can efficiently transport positive electrical charges. These hole-conducting media find increasing applications in unconventional solar ...
The transfer mechanism of 1-pyrene sulfonate anion (PSA−) across the polarized water 1,2-dichloroethane (DCE) interface was investigated by a combination of electrochemical techniques and potential modulated fluorescence (PMF) spectroscopy under total inte ...
Using a density-functional framework, we investigate the vibrational spectra of vitreous SiO2 to determine to what extent these spectra provide information about the medium-range structure of the oxide network. We carry out a comparative study involving th ...
We discuss a detailed near-field spectroscopic study of the nanoscopic optical properties of a novel coupled wire-dot nanostructure grown on (31 1)A GaAs substrates. Photoluminescence spectra recorded with 150 mn spatial and 100 mueV spectral resolution pe ...
Copper and silver cation-exchanged zeolite SSZ-13 present an interesting opportunity to study the mechanism of interaction of adsorbate gases, primarily hydrogen (H2), with the ion-exchange sites in zeolites as there is only one type of cation site, in con ...
Using high-throughput instrumentation to screen conditions, the reaction between FeCl2 and H3BTT·2HCl (BTT3- = 1,3,5-benzenetristetrazolate) in a mixt. of DMF and DMSO gave Fe3[(Fe4Cl)3(BTT)8]2·22DMF·32DMSO·11H2O. This compd. adopts a porous three-dimensio ...
In this thesis, the use of nanotemplates for steering the molecular self-organization at metallic surfaces is investigated. Nanotemplates are surfaces that exhibit a periodic variation of the adhesion energy on the nanometer scale. Preferential adsorption ...
