We have designed and synthesized a modified calixarene derivative (1) that allows, for the first time, the isolation of a stable cation radical salt that binds a single molecule of nitric oxide deep within its cavity with remarkable efficiency (KNO >108 M-1), as demonstrated by isolation of a crystalline complex [1, NO]+ and its characterization by X-ray crystallography as well as by optical spectroscopy. Furthermore, the ready accessibility of the calixarene cation radical will allow the exploration of its use for developing efficient sensing devices for nitric oxide based on the accompanied color changes.
我们设计并合成了一种修饰的杯芳烃衍生物（1），首次实现了稳定阳离子自由基盐的分离，该盐能以极高的效率在其腔内深处结合单个一氧化氮分子（KNO >108 M-1），通过分离结晶复合物[1, NO]+并利用X射线晶体学以及光谱学对其进行表征得以证明。此外，杯芳烃阳离子自由基易于获取，这将有助于探索基于伴随颜色变化开发高效一氧化氮传感装置的用途。
