阳离子荧光探针－－咪唑鎓盐的大环四胺金属配合物的荧光性质研究

Metallic Complexes of macrocyclic polyamine have many special properties, such as the catalyst of DNA cleavage, fluorescence sensor of cation, small molecular sensor and so on. This paper reported that a ligand of macrocyclic polyamine containing a imidazolium salt group respond fluorescence on Cu(II), Zn(II), Co(II) cations in the solution(pydine/water=1:1): fluorescence of Cu(II) complex occurs obvious increase but that of Co(II) and Zn(II) complexes biggish decrease(that of Zn(II) weaken more than that of Co(II)). These complexes have a prosperous potential application in the metal cation sensors field.
