Abstract:

In this paper the interaction of tansinone Ⅱ-A with rare earth metal ions Eu3+、Tb3+ has been studied by several analytical techniques, including 1H NMR T11H NMR and 13C NMR, ultraviolet spectra, and fluorescence spetra. The coordination mechanism of tansinone Ⅱ-A with rare earth metal ions has been
discussed. The experimental results showed that tansinone Ⅱ-A formed stable pentaatomic chelate ring with Eu3+、Tb3+.
