Chelating agents are a crucial ingredient in both nuclear waste remediation and medical imaging. Both of these applications involve the complexation of various f-elements. Our goal is to utilize a type of chelating agent, carbamoylmethylphospine oxides (CMPO's), which are currently used to sequester transuranic elements in the treatment of nuclear waste (the TRUEX process). The research presented in this poster will focus on the synthesis of multidentate ligands bearing three CMPO groups. Our synthetic strategy involves the linking of the CMPO's with a triamino �cap�. We will also include preliminary computational data regarding the structure and relative stability of the resultant metal-ligand complexes.
