With nuclear fuels for electricity production as one proposed solution to reduce global dependence on fossil fuels, there is a pressing need for means of waste remediation and decontamination. New ligands are required that can selectively coordinate actinides for use in applications such as sensing and purifying actinides, including uranium and thorium. This research aims to develop cost-effective ligands for the colorimetric, selective sensing of actinides, incorporating quinoxalines or imine nitrogen donors. We have also prepared complexes with lanthanides for comparison and to study coordination selectivity. The lanthanide complexes of these Schiff bases have been found to provide ideal support for two-photon upconversion, a potential breakthrough that could significantly contribute to the field.
