摘要：

The complexation ability of coumarin 153 linked to monoaza-15-crown-5 was studied. On complexation by alkaline earth metal ions and aluminium ion, both absorption and emission spectra undergo a marked red shift whereas the effects are weaker with alkali metal ions. Owing to the participation of the carbonyl group of the coumarin, the stability of the complexes is much higher than those observed with previously described fluorophores linked to monoaza-15-crown-5. The stability of the complexes remains high enough in acetonitrile-water mixtures for practical application to the determination of cation concentrations in aqueous samples to be possible.
