Abstract/Artist Statement
Among the various ligands in the literature, 1,4,8,11-tetraazacyclotetradecane (cyclam), a saturated macrocylic polyamine ligand, showed great capability in stabilizing transition metal ions. Broadly speaking, investigations into cyclam-derived ligands and their complexes have been initiated by their use in applications in many fields including catalysis, biomimicry, metal recovery and medicine. As a result, its reactivities towards selective metal ion extractions were studied closely here. Metallation of cyclam with a large selection of ions were refluxed in the presence of THF and MeOH solvents. The research has showed that the cyclam ligand can form very stable complexes with first-row transition metal ions. However, when reacted with heavy transition metals, it was difficult to determine the product. This research provided a clean idea about the size of the binding pocket in cyclam and also great hints in functionalizing the ligand sets.
