Lay Summary (German)

Lead
Lay summary
Hintergrund: Kernmagnetische Resonanz Spektroskopie (NMR) ist für präparativ arbeitende anorganische und (metall-)organische ChemikerInnen die wichtigste Technik zur Charakterisierung von neuen Verbindungen. Das beantragte Projekt dient der Erneuerung der NMR-Infrastruktur im Departement Chemie und der Anpassung auf den neuesten technischen Stand. Konkret werden zwei hochmoderne, digital arbeitende NMR-Spektrometer Konsolen angeschafft, die für zahlreiche Projekte im Departement Chemie unentbehrlich sind.Ziel: Die neuen NMR-Spektrometer sollen bei folgenden konkreten Fragestellungen eingesetzt werden:- Untersuchungen zur Wechselwirkung zwischen Proteinen untereinander und zwischen Proteinen und kleinen Molekülen mittels pramagnetischen Effekten in NMR Experimenten, die die Charakterisierung von Wechselwirkung in bislang aufgrund Ihrer Komplexität unzugänglichen Problemen ermöglichen soll (grosse Proteine, schwache Wechselwirkungen)- Aufklärung der Struktur und daran anschliessende Synthese neuer Naturstoffe mit neuartigen Architekturen, die ungewöhnliche Eigenschaften als Wirkstoffe aufweisen.- Mechanistische Untersuchungen an Iridium-Katalysatoren die zur asymmetrischen Hdryrierung ungesättigter Kohlenwasserstoffe eingesetzt werden.- Strukturelle und mechanistische Experimente, die zur Entwicklung künstlicher Metallo-Enzyme auf der Basis der Streptavidin-Biotin Interaktion führen sollen.- NMR basierte Charakterisierung der Molekülgrösse in Metallo-Polymeren und Metallo-Macrozyklen.Bedeutung: Die Aufwertung der NMR-Infrastruktur ist von entscheidender und kritischer Wichtigkeit für die Durchführung der oben angeführten Untersuchungen. Die breitgefächerten Forschungsprojekte dienen der detailierteren Einsicht in relevante Grundlagen der Wechselwirkung zwischen Molekülen, der Entwicklung neuer Wirkstoffe und Materialien, sowie resourcenschonender Katalysatoren.

Abstract

The requested funding will be used for the replacement and upgrading of our dedicated research NMR instrumentation at the department of chemistry (500 and 600 MHz spectrometers). All of the five applicants use NMR as a key technique and critically rely on sufficient experiment time on state of the art technology spectrometers. Detailed information on the mechanistic and structural investigations that are carried out in the fields of natural product research, paramagnetic protein NMR, artificial enzymes, asymmetric organometal catalysis, metallopolymers, and supramolecular chemistry are provided, to unambiguously demonstrate the necessity and the potential achievements that can be expected from the desired upgrade.
