{"abstract":[{"lang":"eng","text":"Surface enhanced solid-state NMR by dynamic nuclear polarization (DNP SENS) enables the characterization of the inner-pore surface functionalization of porous etched ion-track membranes exhibiting low specific surface areas compared to typical SBA- or MCM-type mesoporous silica materials. The membranes were conformally coated with a 5 nm thin SiO2 layer by atomic layer deposition. This layer was subsequently modified by aminopropyl silane linkers that allow further functionalization via the terminal amine group. The results evidence that in principle DNP SENS is a capable tool to analyze more complex porous systems, e.g. bioinspired functional etched ion-track membranes down to the molecular level. These results are relevant also for single nanopore systems, for which a direct analysis of the channel surface functionalization is not feasible by classical characterization methods. The applicability of DNP SENS to complex porous systems requires the optimization of the sample preparation and measurement parameters."}],"status":"public","publication":"Zeitschrift Fur Physikalische Chemie-International Journal of Research in Physical Chemistry & Chemical Physics","type":"journal_article","language":[{"iso":"eng"}],"extern":"1","_id":"64000","user_id":"100715","year":"2018","intvolume":"       232","page":"1173–1186","citation":{"apa":"Kumari, B., John, D., Hoffmann, P., Spende, A., Toimil-Molares, M.
