摘 要: 通过乙二胺四乙酸二酐(EDTAA)与对苯二胺进行酰化聚合,得到相对分子质量适中的寡聚乙二胺-N,N′-二(乙酰苯胺)-二乙酸。以此寡聚物为配体与GdCl3反应得到相应的寡聚钆(Ⅲ)配合物。通过元素分析、FT-IR、1HNMR及热重-差热分析对配体和配合物的组成和结构进行了表征。 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.
