The stability of the α-nitronyl nitroxide radical unit under acidic conditions is investigated by an integrated experimental UV/Vis spectroscopy and TDDFT study. In the field of molecular magnetism, α-nitronyl nitroxide radicals are important as purely organic spin carriers due to their synthetic versatility. Here, the existence of an intermediate of the protonated α-nitronyl nitroxide radical unit is demonstrated for the first time and a proposed disproportionation reaction is confirmed.
通过集成实验 UV/Vis 光谱和 TDDFT 研究，考察了α-硝酮氮氧自由基单元在酸性条件下的稳定性。在分子磁性领域，由于其合成的多功能性，α-硝酮氮氧自由基作为纯有机自旋载体是很重要的。在这里，首次证明了质子化的α-硝酮氮氧自由基单元的中间产物的存在，并证实了所提出的歧化反应。
