A flexible cylindrical cryptand () with two -phenylene-26-crown-8 ethers has been prepared, and its complexing properties with respect to tetravalent cationic bis-paraquat guests have been investigated. Diffusion-ordered spectroscopy nuclear magnetic resonance (NMR) and titration experiments using cold electrospray ionization mass spectrometry and H NMR revealed that has versatile complexing properties with respect to tetravalent cationic guests used despite the guest molecules' length and shape.
一种具有两个 - 亚苯基-26-冠-8 醚的柔性圆柱形cryptand()已被制备,并研究了其与四价阳离子双对醌客体的络合性质。扩散有序光谱核磁共振(NMR)和使用冷电喷雾电离质谱和 H NMR 的滴定实验表明,尽管客体分子的长度和形状不同,但 对所用的四价阳离子客体具有多种络合性质。
