本文报道1^H、7^Li、23^Na、133^Cs NMR测定N, N'-二羧甲基大环醚双内酯(1-4)和大环胺双内酰胺(5), N-对甲苯磺酰基大环醚双内酯(6, 7), 4'-丹磺酰氨基苯并-18-冠-6(8)与Li^+、Na^+、K^+、Cs^+、Cd^2+和Pb^2+金属离子的配位作用, 并以非线性最小二乘法拟合计算了配合物的形成常数; 同时, 发展了一种用133^Cs NMR测量冠醚和碘离子竞争配合Cs^+的配合物形成常数的新技术。

The complexations of N,N-dicarboxymethyl macrocyclic ether-bislactones and amine-bislactam, N-tosyl-macrocyclic ether-bislactones, and 4'-(dansylamin)benzo-18-crown-6 with Li+, Na+, K+, Cs+, Cd2+ and Pb2+ ions were studied by 1H, 7Li, 23Na, 133Cs NMR and the formation constants of complexes were calculated by nonlinear-least-squares program KINFIT. Also a 133Cs NMR technique was developed for the measurement of formation constants of crown ether complexes that uses competition of a crown ether and I- for a given Cs+.
