摘要
本文报道12种稀土(Y、La、Ce、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Er、Yb)—罗丹明B的固体配合物制备,通过元素分析、溶解度及摩尔电导测定、差热热重分析、X-射线衍射、红外、紫外、可见、荧光光谱以及~1HNMR谱等对它们的配位作用和性质进行了研究。
Twelve solid coordination compounds of RE(Y,La,Ce,Pr,Nd,Sm,Eu,
Gd,Tb,Dy,Er,Yb)with Rhodamine B were prepared.Their compositions were
confirmed by elemental analysis,molar conductance,and thermal analysis.
Coordination between the ligand and the RE ion was proved by X-ray powder
diffraction and UV spectra.The coordinated function groups of the ligand were
examined by IR and ~1H NMR spectra.
