摘要

In the objective of optimizing water exchange rate on stable, nine-coordinate, monohydrated GdIII poly (amino carboxylate) complexes, we have prepared monopropionate derivatives of DOTA4−(DO3A-Nprop4−) and DTPA5−(DTTA-Nprop5−). A novel ligand, EPTPA-BAA3−, the bisamylamide derivative of ethylenepropylenetriamine-pentaacetate (EPTPA5−) was also synthesized. A variable temperature 17O NMR study has been performed on their GdIII ...
