title: Ligand-triplet-fueled long-lived charge separation in ruthenium(II) complexes with bithienyl-functionalized ligands.
abstract: Ruthenium(II) polypyridyl complexes with pendant bithienyl ligands exhibiting unusually long-lived (τ ~ 3-7 μs) charge-separated excited states and a large amount of stored energy (ΔG° ~ 2.0 eV) are reported. A long-lived ligand-localized triplet acts as an energy reservoir to fuel population of an interligand charge-transfer state via an intermediate metal-to-ligand charge-transfer state in these complexes.
