  text: <jats:p>The effects of backbone amine functionalization in three new homoleptic
    C^N^C type ruthenium(II) complexes bearing a tridentate bis‐imidazole‐2‐ylidene
    pyridine ligand framework are characterized and studied by single crystal diffraction,
    electrochemistry, optical spectroscopy and transient absorption spectroscopy in
    combination with ab initio DFT calculations. Functionalization by dimethylamine
    groups in 4‐position of the pyridine backbone significantly influences the properties
    of the complexes as revealed by comparison with the unfunctionalized references.
    As a result of the amine functionalization, a higher molar absorption coefficient
    of the MLCT bands, a decreased photoluminescence quantum yield at room temperature
    together with a shortened excited state lifetime but an improved photostability
    is observed. Introduction of electron donating and withdrawing groups at the NHC
    unit modifies the electronic and optical properties, such as the oxidation potential,
    absorption and emission properties, and the lifetimes of the excited states.</jats:p>
