摘要：

The complexation equilibria of divalent and lanthanoid metal ions with 1,2-bis(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (BAPTA) and 2-[(2-amino-5-methylphenoxy)methyl]-6-methoxy-8-aminoquinoline-N,N,N',N'-tetraacetic acid (quin2) were studied by pH titration. In lanthanoids, BAPTA shows a maximum stability for Pr3+, whereas quin2 has higher affinities for heavier ones. These trends are discussed in terms of the rigidity and donor atoms of these ligands. Intense fluorescence was observed for quin2 complexes of Group-2 and -3 elements. Among the lanthanoids, only Sc, Y, La, Gd, and Lu enhance the fluorescence at around 380 nm.
