14N NMR spectroscopy study of binding interaction between sodium azide and hydrated fullerene
(MDPI, 2017)Our study is the first attempt to study the interaction between NaN3 and hydrated fullerenes C60 by means of a non-chemical reaction-based approach. The aim is to study deviations of signals obtained by 14N NMR spectroscopy ... -
1D to 2D Self Assembly of Cyclic Peptides
(American Chemical Society, 2020)Despite recent developments in two-dimensional self-assembly, most supramolecular 2D materials are assembled by tedious methodologies, with complex surface chemistry and small sizes. We here report d/l-alternating cyclic ... -
(1RS,4RS,5RS)-Methyl 2-(3,5-dinitrobenzoyl)-2-oxa-3-azabicyclo[3.3.0]oct-7-ene-4-carboxylate
(International Union of Crystallography, 2009)In organic synthesis, the usual techniques as NMR, mass or infra-red spectrometry and elemental analysis are often not enough for the unequivocally determination of a structure of a compound. When it is possible to ... -
