With 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.

Abstract
With 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
