Oxygen-17 and deuterium are two quadrupolar nuclei that are of interest for studying the structure and dynamics of materials by solid-state nuclear magnetic resonance (NMR). Here, 17 O and 2 H NMR analyses of crystalline ibuprofen and terephthalic ac

In recent years, there has been increasing interest in developing cost‐efficient, fast, and user‐friendly 17O enrichment protocols to help to understand the structure and reactivity of materials by using 17O NMR spectroscopy. Here, we show for th

International audience; Previous studies have demonstrated that functionalised T8 polyhedral oligomeric silsesquioxanes with fluoride anions encapsulated within the T8 cage (T8-F) have very low reactivity, with no reports of successful modification o

Despite the extensive range of investigations on boronic acids (R-B(OH)2), some aspects of their reactivity still need to be explored. This is the case for the coordination chemistry of boronate anions (R-B(OH)3−), which has only recently been star

While oxygen-17 NMR is increasingly being used for elucidating the structure and reactivity of complex molecular and materials systems, much effort is still required for it to become a routine analytical technique. One of the main difficulties for it
