•Synthesis of red/near-IR emissive RuII isocyano complexes of quinoline-8-thiolate.•X-ray structures for the geometrical isomers of the RuII isocyano complexes.•Photophysical properties on varied ligand electronic nature and isomerism.•Electrochemical properties on varied ligand electronic nature and isomerism.•DFT calculation of molecular orbitals of geometrical isomers.
The reactions of [RuII(SQ)2(PPh3)2] (SQ = quinoline-8-thiolate) with different isocyanide ligands affords a series of emissive bis(quinoline-8-thiolate) ruthenium(II) complexes [RuII(SQ)2(PPh3)(CNR)] (1–6). Two isomeric forms, i.e. cis,trans (1a – 6a) and cis,cis (1b – 6b) have been separated in these reactions. With the variation on the π-accepting ability of the isocyanide ligands, the CN stretches, lowest energy absorptions and the photoluminescence can be systematically modified.
