title: Direct EPR observations of both oxidized and reduced porphyrin dimers in the lowest excited states: a novel analysis of a homobiradical with a strong antiferromagnetic interaction.
abstract: The oxidized and reduced forms of bis(tetra-tert-butyltetraazaporphinato)lutetium (III) (Lu(TAP)2) have been examined by time-resolved EPR (TREPR) spectroscopy, showing both the first EPR investigation of a homobiradical with a strong antiferromagnetic interaction and usefulness of TREPR for investigating excited-state properties of different oxidation states.
