2-苯基喹啉-4-甲酸稀土配合物的研究

Studies on the Complexes of Rare Earths with 2-Phenyl-Quinoline-4-Carboxylic Acid

制备了十五种稀土与2-苯基喹啉-4-甲酸的配合物,确定其组成为REA_(3)·2H_(2)O(RE=Y,La-Nd,Sm-Lu,A=C_(16)H_(10)NO_(2)^(-));研究了IR、UV、H-NMR、分子荧光光谱、摩尔电导、溶解性及热稳定性等。

The fifteen complexes of rare earth with 2-phenyl-quinoline-4-carboxylic acid have been prepared.The composition of complexes has been determined as RE(C_(16)H_(10)NO_(2)^(-))_(3)·H_(2)0(RE=Y,La-Nd,Sm-Lu).The IR,UV,H-NMR,TG and DTA,molecular fluorescence spectra,molecular conductance of these complexes in DMF and DMSO,and their solubilities in H_(2)O and organic solvents of the complexes have also been studied.
