Abstract:

Because the unique spatial confinement, easy assembly and multi-functional features of cage-like metal-organic complexes, there is an important advantage for the selective recognition of small biological molecules. Here we reported a organic ligand L2 which has a high degree of symmetry, and got two zinc/cobalt-based cage-like complexes Zn-L2/Co-L2 through complexation with transition metal ions Zn / Co. These two cage-like complexes Zn-L2 and Co-L2 are tetrahedron on geometry which have with optical activity. The tetrahedral complexes Zn-L2/Co-L2 are cationic cage-like complexes to studied the recognition for biological small molecules nucleotide. By means of fluorescence to study the interaction between nucleotide and tetrahedral complexes Zn-L2/Co-L2, we found that there were three aniline significantly enhanced fluorescence signal when only adenosine triphosphate molecule ATP was added. The tetrahedral complexes Zn-L2/Co-L2 are the selective recognition of ATP.
