【Abstract】 Macromolecular ligands were prepared by the condensation polymerization of diethylenetriaminepentaacetic dianhydride with long chain Llysine alkyl esters. The corresponding paramagnetic metal complexes were also prepared by the reaction of these ligands with GdCl3. The relaxivities of these metal complexes are higher than that of Gd(DTPA).更多还原
