Reactions of 12-crown-4, 15-crown-5, 18-crown-6, and 21-crown-7, as well as the acyclic analogs triglyme, tetraglyme, and penta(ethylene glycol), with Li + , Na + , K + , Rb + , and Cs + , are observed and characterized using Fourier transform ion cyclotron resonance mass spectrometry (FTICR/MS) and tandem quadrupole mass spectrometry in the gas phase to obtain information on intrinsic host-guest interactions
12-crown-4、15-crown-5、18-crown-6 和 21-crown-7 以及无环类似物三甘醇二甲醚、四甘醇二甲醚和五(乙二醇)与 Li + 、Na + 的反应、K + 、Rb + 和 Cs + ,在气相中使用傅立叶变换离子回旋共振质谱 (FTICR/MS) 和串联四极杆质谱法进行观察和表征,以获得有关内在主客体相互作用的信息溶剂化的复杂影响。阳离子与配体的辐射稳定连接是一个快速过程,在某些情况下,其速率是朗之万碰撞速率的 2 倍或更多倍
