The complexing properties of compounds 10a, 10b, 11a and 11b toward alkali metal ions were studied by 〓H NMR titration, ESI-MS, UV-Vis spectra, Fluoresence spectra and liquid-liquid extraction. The results show:(1) the 1:1 complexes were formed.(2) The calix-crown 10a, 11a have a higher selectivity for Na〓 ions, whereas 10b, 11b for K〓 ions.(3) The complexing ability toward alkali metal ions was enhanced when the calix-crown have side arm carbonyl.(3) The coordination of alkali metal ions toward phenoxy, carbonyl and crown ethereal oxygens take place by rotation around the carbon-carbon bond of carbonyl and methylene.

六,用〓H NMR滴定,ESI-MS,UV-Vis,Fluorescence,液-液萃取实验研究了10a,10b,11a和11b对金属离子的配位性质,研究结果表明:1)杯芳烃冠醚衍生物同碱金属离子形成了1:1配合物,化合物10a、11a对Na〓具有较高的配位能力,化合物10b、11b对K〓具有较高的配位能力;2)在杯冠醚环的旁边引入带有羰基氧原子的基团作为侧臂参与配位可以加强对碱金属离子的配位能力;3)金属离子分别同苯酚氧,羰基氧,聚氧醚链氧发生了配位,配位过程中侧链基团涉及到了羰基碳与亚甲基碳的碳碳键的旋转过程。
