Luminescent rhenium(I) complex of azo ligand based on quinoline: Synthesis, characterization and computational investigations
Reaction of 7-(quinolin-8-yldiazenyl)quinolin-6-ol HL, [where H represents the dissociable proton upon complexation] based on quinoline with [Re(CO)5Cl] in toluene afforded brown colored product of composition [(Re(CO)3L]. The mononuclear Re(I) complex was characterized unequivocally. Molecular structure of the complex fac-[(Re(CO)3L] was confirmed by single-crystal X-ray diffraction. The complex exhibited excellent photoluminescence behavior in solution state. The ground and excited-state geometries and absorption properties of the Re(I), complex was further examined by DFT and TDDFT methods
