α-酮戊二酸-2、4-二硝基苯腙稀土配合物的合成与表征
摘要:
报道了T-酮戊二酸-2,4-二硝基苯腙(H2LPN)配体及它的5种稀土配合物(La、Pr、Nd、Eu和Gd)的合成,并采用元素分析、IR、UV、1H NMR和DTA-TG对配合物进行了表征.通过INVREC.Au程序用反转恢复法测定Gd3+配合物弛豫效率.

Synthesis and Characterization of Polycarboxylic Hydrazone Rare Earth Complexes
Abstract:
The synthesis of a ligand, T-oxo pentanedioic acid-2,4-dinitrobenzene hydrazone(H2LPN), and its five rare earth (La,Pr,Nd,Eu and Gd) complexes are reported. The complexes are characterized by element analysis, IR, UV and 1H NMR spectra, thermal analysis. Besides, the relaxivity of Gd3+ complex was determined by INVREC.Au program, using inversion recovery pulse sequences.
