Synthesis and Characterization of <sup>15</sup>N‐Labeled Poly(sulfur nitride) in Bulk and in Superconductor Composites
Abstract
<jats:title>Abstract</jats:title><jats:p><jats:sup>15</jats:sup>N‐labeled tetrasulfur tetranitride (S<jats:sub>4</jats:sub><jats:sup>15</jats:sup>N<jats:sub>4</jats:sub>) was synthesized by reacting S<jats:sub>2</jats:sub>Cl<jats:sub>2</jats:sub> with <jats:sup>15</jats:sup>NH<jats:sub>3</jats:sub>. The reaction was finalized with <jats:sup>14</jats:sup>NH<jats:sub>3</jats:sub>. The successful labeling was confirmed by solution <jats:sup>15</jats:sup>N nuclear magnetic resonance (NMR) spectroscopy. S<jats:sub>4</jats:sub><jats:sup>15</jats:sup>N<jats:sub>4</jats:sub> was used for the synthesis of poly(sulfur nitride) S<jats:sup>15</jats:sup>N<jats:italic><jats:sub>x</jats:sub></jats:italic> via the intermediate species of S<jats:sub>2</jats:sub>N<jats:sub>2</jats:sub>. It was a topochemical polymerization in the solid state. The isotope ratio in the labeled polymer was obtained by laser deposition ionization time‐of‐flight mass spectroscopy. Solid‐state <jats:sup>15</jats:sup>N NMR spectroscopy of S<jats:sup>15</jats:sup>N<jats:italic><jats:sub>x</jats:sub></jats:italic> indicates that at least three different chemical environments for <jats:sup>15</jats:sup>N atoms are present in the crystals. Finally, SN<jats:italic><jats:sub>x</jats:sub></jats:italic> was polymerized in the presence of two other superconductors, MgB<jats:sub>2</jats:sub> and yttrium barium copper oxide (YBCO), which demonstrates the capability of SN<jats:italic><jats:sub>x</jats:sub></jats:italic> for grain boundary engineering.</jats:p>
