Synthesis, properties and applications of single-component anion-exchange materials
Several tetraalkylated ferrocenium salts and neutral modified ferrocenes, both new and previously synthesized, were studied in detail. Some of these salts have been used in the past as anion-exchange extractants for attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. …

Investigation of Electronic Molecular Materials with Magneto-Optical and Magnetic Properties
… composites. We discuss the development of ferrocenium-based optical-quality thin films, their resulting MO responses, and the desirable and unique MO features of C-term materials geared toward applications. In Chapter 3, we expand on the work established in Chapter 2 by developing …

Mechanistic studies and design of supported transition metal complexes
… can be exploited to increase selectivity of ferrocenium (Fc⁺)-based polymer electrode materials for formate adsorption over perchlorate adsorption while maintaining reasonable desorption rates in the reduced (ferrocene, Fc) state. Through a systematic characterization of formate and …

Design and synthesis of handles for solid-phase peptide synthesis and convergent peptide synthesis
… was investigated based on the stability of the ferrocenium ion. The stability of this ion is greater than that of the benzyl cations that are used in the handles developed previously.

Bildung und Nutzung multinuklearer Titanocenkomplexe mit N-heterocyclischen Brückenliganden
… been established by stochiometric reactions with ferrocenium salts as one electron oxidants. Thereby a number of mixed valence states have been shown to be accessible and were isolated as crystalline compounds. This allowed first investigations on the extent of electronic communication between …

Path integral methods for quantum dynamics in condensed phases
… various anharmonic effects, Ferrocene (donor) - Ferrocenium (acceptor) system in liquid Benzene was studied where the anharmonic effects of the bath of liquid Benzene on the dynamics of the system were treated using Ensemble Averaged Classical Path. The process of electron or proton transfer …

Electrochemically-mediated membrane separations for carbon dioxide capture
… quinone reduction to ferrocene oxidation and ferrocenium reduction to dianion-adduct oxidation using graphite electrodes. A bench-scale test cell has been designed and built to demonstrate electrochemical carbon capture in a cell with laminar flow of the electrolyte. The quinone-ferrocene …

Organometallic redox-interfaces for selective electrochemical separations
… unraveled the unique binding mechanism between ferrocenium and organic ions demonstrating an unusual redox-mediated hydrogen-bonding between cyclopentadienyl and carboxylates; and utilize this knowledge to further tune our redox-systems to enhance chemical selectivity. We expanded our …

Ferrocenyl derivatives of dithizone : photochromic properties and potential as electrochemical sensors
… wave in acetonitrile assigned to the ferrocene/ferrocenium couple: for receptor (13), E1I2 = 203 mV and for receptor (14), E1I2 = 136 mV relative to ferrocene as a standard reference. Addition of Cu2 + ions to ligand solutions in acetonitrile showed contrasting behaviour: ligand (13) produced a …

Spectroscopic and functional models for Hmd hydrogenase
… yields. The Fe(P2O2)(CO)2 complex reacts with (ferrocenium)BF4 to give a 50% conversion to a complex with BF3 bound to each alkoxide. The mechanism for this reaction is proposed to involve an iron mediated F- abstraction from BF4-. The binding of Lewis acids to the alkoxides was found to be …
