TL;DR: 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.

TL;DR: In this paper, the steric repulsion-based tuning of the central dihedral angle was used to control the optical and electro-optic responses of twisted, merocyanine-type molecules.

TL;DR: A systematic synthesis approach for preparing a family of Ru(II) polypyridyl complexes of the type 4,4'-R2-bpy, modified through the incorporation of electron-donating or electron-withdrawing functionalities to tune redox potentials and excited-state energies.

TL;DR: A quantitative computational analysis shows that a near-resonant charge transfer regime, wherein a mix of superexchange and hopping mechanisms are expected to coexist, can rationalize all of the experimental results.

TL;DR: DFT calculations confirm the structure and indicate that there is no agostic bonding between the ortho isopropyl methinyl hydrogens and the Sn atom, and calculation of the 119Sn chemical shift is in good agreement with the observed value.
