合成了双亚苯基-26-冠-8-醚的柔性圆柱形配合物(1b)，并研究了它与四价阳离子双百草枯客体的络合性能。扩散有序光谱、核磁共振以及冷电喷雾电离质谱仪和~1H核磁共振的滴定实验表明，无论客体分子的长度和形状如何，1b对所使用的四价阳离子客体都具有多种络合性能。
A flexible cylindrical cryptand (1b) with twom-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 and1H NMR revealed that1bhas versatile complexing properties with respect to tetravalent cationic guests used despite the guest molecules’ length and shape.
