| 摘 要： | 本文通过二乙三胺五乙酸（ＤＴＰＡ）或乙二胺四乙酸（ＥＤＴＡ）的双酸酐与二元醇或二元酚进行聚合反应，制备了两个系列共１５种新的聚酯型大分子配体及其顺磁性金属配合物，用核磁、红外光谱以及元素分析表征了配体和配合物的结构。初步试验结果表明，与相应的小分子金属配合物相比，聚酯金属配合物具有较高的弛豫性能。

| Abstract: | Fifteen new polyester ligands were prepared by polymerization of EDTA(ethylenedlaminetetraacetic acid ) dianhydride or DTPA (diethylenetriaminepentaacetic acid) dianhydride and dihydric alcohol or dihydric phenol. Theirparamagnetic metal complexes were also synthesized. All polyester ligands andmetal complexes were characterized by IHNMR, IR spectra and elemental analyses. Preliminary study showed that the Polyester metal complexes had higher relaxation effectiveness as compared to corresponding small molecular metal complexes. |
