用分光光度法测得,在乙醇介质中Nd~(3+)Hpmbp(1苯基-3-甲基-4-苯酰吡唑酮-5)—有机碱(二苯胍或季铵碱)和Nd~(3+)—二苯酰甲烷(DBM)—四乙基碘化铵(TAI)系统中形成了Nd~(3+):β_二酮:有机碱=1∶4∶1的离子缔合物。它们的超灵敏跃迁振子强度的增大规律与异配络合物相同。根据Judd-ofelt理论计算了Nd~(3+)-DBM-TAI系统的τ_2,τ_4,τ_6参数值,并揭示了镧(Ⅲ)系三元络合物超灵敏跃迁振子强度的增大(△P)与τ_2增大的相关性。还讨论了应用超灵敏跃迁振子强度增大规律,推断三元络合物组成的可能性。
Spectrophotometric determination of Nd ~ (3 +) Hpmbp (1-phenyl-3-methyl-4-benzoylpyrazolone-5) -organic base (diphenylguanidine or quaternary ammonium hydroxide) And Nd ~ (3 +): β_dione: organic base = 1: 4:1 in the system of Nd ~ (3 +) - dibenzoylmethane (DBM) -tetraethylammonium iodide Ion association. The amplitudes of their super-sensitive transition oscillator strengths are the same as heteroleptic complexes. The values of τ_2, τ_4 and τ_6 of Nd ~ (3 +) - DBM-TAI system were calculated according to the Judd-ofelt theory and the increase of the super-sensitive oscillator strength of the ternary complex of lanthanum (Ⅲ) P) with increasing τ_2. We also discuss the possibility of using the law of increasing the oscillator strength of hyper-sensitive transitions to deduce the composition of ternary complexes.
