本文对四种不同的4—酰代双吡唑酮为配体的稀土二元和三元配合物的荧光性质进行了较系统的研究和比较,发现4—酰代双吡唑酮配体和第二配体的性质,配合物的结构、类型以及溶剂的性质均是影响配合物荧光强度的重要因素。在所研究的配合物中,不同4—酰代双吡唑酮配合物荧光强度的变化顺序为BPMPPD>BPMPHD>BPMPBD>BPMPTD。一般三元配合物的荧光强度比二元配合物的大,离子缔合型配合物的大于加合配位型的,单核配合物的大于同双核配合物的。加入其它稀土离子形成异双核配合物时,La、Gd、Lu和Y对配合物荧光有增强作用,而Nd、Ho和Er对配合物荧光起猝灭作用。
In this paper, four different 4-acylpyrazolone ligands for the rare earth binary and ternary complexes of the fluorescence properties of a more systematic study and comparison and found that 4-acyl bi-pyrazolone ligand and The nature of the second ligand, the structure and type of the complex, and the nature of the solvent are both important factors affecting the fluorescence intensity of the complex. In the studied complexes, the order of fluorescence intensity of different 4-acylated bispyrazolone complexes is BPMPPD> BPMPHD> BPMPBD> BPMPTD. Fluorescence intensity of the general ternary complexes than the binary complexes, ion-associative complexes greater than the adduct, mononuclear complexes than the same binuclear complexes. La, Gd, Lu and Y enhance the fluorescence of the complexes when other rare earth ions are added to form heterobuclei complexes, while Nd, Ho and Er quench the fluorescence of the complexes.
