In 1974, the metal-to-ligand charge transfer (MLCT) excited state, [Ru(bpy)3]2+*, was shown to undergo electron transfer quenching by methylviologen dication (MV2+), inspiring a new approach to artificial photosynthesis based on molecules, molecular-level phenomena, and a “modular approach”. In the intervening years, application of synthesis, excited-state measurements, and theory to [Ru(bpy)3]2+* and its relatives has had an outsized impact on photochemistry and photophysics. They have… 

Controlling ground and excited state properties through ligand changes in ruthenium polypyridyl complexes.

The synthesis, characterization, electrochemical, and photophysical properties of a series of Ru(II) polypyridyl complexes of the type [Ru(bpy)2(N-N)](2+) are reported, with electrochemical measurements showing that lowering the π* orbitals on the N-N ligand results in more positive Ru(3+/2+) redox potentials and more positive first ligand-based reduction potentials.

Unexpected Role of Ru(II) Orbital and Spin Contribution on Photoinduced Ligand Exchange: New Mechanism To Access the Photodynamic Therapy Window

A series of 12 Ru(II) complexes of the type [Ru(tpy)(L)(CH3CN)]n+, 1–12, containing the tridentate tpy ligand (tpy = 2,2′:6′,2″-terpyridine) and various bidentate ancillary ligands, L, were

How Does Peripheral Functionalization of Ruthenium(II)-Terpyridine Complexes Affect Spatial Charge Redistribution after Photoexcitation at the Franck-Condon Point?

This work explores the nature of the (1) MLCT states of remotely substituted Ru(II) model complexes by both experimental and theoretical techniques, and reveals different properties of the optically active bright ( 1)MLCT states already at the Franck-Condon point.

Unravelling the role of [Ru(bpy)2(OH2)2]2+ complexes in photo-activated chemotherapy.

Photoactivated chemotherapy (PACT) has emerged as a promising strategy to selectively target cancer cells by using light irradiation to generate cytotoxic complexes in situ through a mechanism

Photocatalytic hydrogen evolution using a Ru(II)-bound heteroaromatic ligand as a reactive site.

Density functional theory (DFT) and time-dependent DFT calculations on the reaction mechanism of H2 evolution from the ground and photo-excited states of 2 were performed to have a better understanding of the photocatalytic processes.

Excited-State Decay Pathways of Tris(bidentate) Cyclometalated Ruthenium(II) Compounds.

Molecules of this type represent a robust class of compounds with built-in design features that should greatly enhance the molecular photostability necessary for photochemical and photoelectrochemical applications and provide compelling evidence that LF states are not significantly populated near room temperature unlike many ruthenium(II) polypyridyl compounds.

Chemical control of competing electron transfer pathways in iron tetracyano-polypyridyl photosensitizers†

This study demonstrates that the excited state relaxation mechanism of Fe polypyridyl photosensitizers can be readily tuned by ligand and solvent environment and reveals that extending charge transfer lifetimes requires control of the relative energies of the 3 MLCT and the 3MC states and suppression of the intramolecular distortion of the acceptor ligand in the 3MLCT excited state.

Unusual Role of Excited State Mixing in the Enhancement of Photoinduced Ligand Exchange in Ru(II) Complexes.

Four Ru(II) complexes were prepared bearing two new tetradentate ligands, cyTPA and 1-isocyTPQA, which feature a piperidine ring that provides a structurally rigid backbone and facilitates the

HERFD-XANES probes of electronic structures of ironII/III carbene complexes.

The results show how the combination of experimental HERFD-XANES measurements and ab initio RAS simulations can give quantitative evaluation of the orbital interactions between metal and ligands for such large and strongly interacting systems and thus allow to understand and predict properties of novel complexes.
