Abstract
The oligomeric ethylenediamine-N,N'-dis(acetyl-p-aniline)-N,N'-diacetic acid with a moderate molecular weight was prepared through acylated polymerization between ethylenediamine tetraacetic acid dianhydride(EDTAA)and p-phenylene diamine.The oligomeric ligand reacted with GdCl3·6H2O to afford the oligomer of Gd(Ⅲ)complex.The composition and structure of this new ligand and Gd(Ⅲ)complex were characterized by elemental analysis,FT-IR,1HNMR and TG-DTA analysis.
