2,2'-联咪唑衍生物铜配合物的合成、表征及光谱性质

Synthesis,characterizeation and spectral properties of copper(Ⅱ) complexes containing 2,2'-biimidazole derivation ligands

本文合成了1,1'-二(丙酸甲酯)-2,2'-联咪唑和1,1'-二(丙酸乙酯)-2,2'-联咪唑两个配体,并以无水乙醇为溶剂,在常温条件下合成了配体与铜的配合物。通过IR、UV、EA表征,推测其形成了1:1的配合物。铜配位后使两种配体发生荧光猝灭。

Two new complexes [Cu（DMPB）（NO3）2] and [Cu （DMPB）（NO3）2] have been prepared in absolute ethanol at room temperature （ DMPB= 1,1′-di（methylpropionato） -2,2′-biimidazole, DEPB= 1,1′-di（ethylpropionato） -2,2′-biimidazole）. The complexes have been characterized by IR spectra, UV-vis spectra and elemental analysis. The results show that the complexes are consisted of Cu and ligands with the ratio of 1：1 and the complexes formation can results in fluorescence quenching of ligands.
