Abstract

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 T₁, ¹H 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⁺.

Key words:

Tansinone Ⅱ-A, Eu^3+, Tb^3+, Metal ions, Complexes, NMR

CLC Number:
