【摘要】 <正> 荧光素类分子中含有羧基和羟基,可与多种金属离子形成络合物。荧光素及碘代荧光素的镧系络合物的性质已进行过研究。最近虽报道了其镧系络合物的制备,但未见有关组成和性质等方面的记载。我们制取了12种四氯四碘荧光素镧系络合物,通过元素分析确定了其化学组成,并探讨了它们的溶解性能、电导、热重、红外光谱和紫外-可见光谱等性质。更多还原

【Abstract】 A series of lanthanide (except Ce,Pm,Lu) complexes of rose bengal were prepared inalcohol: water(2: 3)solution. The composition of these complexes have been ascertained byelemental analysis. Some properties, such as IR spectra, UV spectra, electric conductivities,TG curves and solubilities in different solvents were measured.更多还原
