摘要
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.
