合成了2个新型的多齿配体:2,9-二-[1’-(2″-苯并咪唑基)-2’-氮杂-正丙基]-1,10-菲罗啉(L1)和2,9-二-[2’-(2″-苯并咪唑基)-3’-氮杂-正丁基]-1,10-菲罗啉(L2)并且用元素分析和1HNMR谱作了表征。在25±0.1℃,运用pH电位滴定法对这2个新的配体及其与过渡金属离子M髤(M=Co,Ni,Cu,Zn)和稀土金属离子Ln髥(Ln=La,Nd,Sm,Eu,Gd)的配合物进行了热力学稳定性研究。结果表明配体和金属离子的配位比为1∶1,但是,这2个系列的配合物在稳定性方面存在很大差异。
Two novel polydentate ligands were synthesized: 2,9-bis- [1 ’- (2 “-benzimidazolyl) -2’-aza-n-propyl] -1,10-phenanthroline L1) and 2,9-bis- [2 ’- (2 ”-benzimidazolyl) -3’-aza-n-butyl] -1,10-phenanthroline (L2) Spectrum was characterized. At 25 ± 0.1 ℃, the two novel ligands and their interaction with transition metal ions M 髤 (M = Co, Ni, Cu, Zn) and rare earth metal ions Ln 髥 (Ln = La, Nd , Sm, Eu, Gd) complexes were studied thermodynamically. The results show that the ligand and metal ion coordination ratio of 1: 1, but the two series of complexes in the stability there is a big difference.
