CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWith the aim of obtaining new molecules that could form nanomaterials through intermolecular aggregations in the solid state, we prepared some oligomers of the Boc-(L-Phe-D-Oxd)n-OR series with the expectation that the presence of phenyl groups could favour aggregation by means of NH hydrogen bonds and/or pi-stacking interactions. We can show that fibers or fibrils are formed dependent on the length of the foldamer chain. The chemical properties of these compounds have been examined in the solid phase utilizing X-ray diffraction, solid state NMR, SEM, and TEM microscopy. Theoretical calculations have been performed to explain the results.
