The coordination behavior and fluorescence spectra of pyrene-appended Schiff bases and the ruthenium(II) complexes were studied. The study was done with two generic types of ruthenium(II) precursor with different set of Lewis base ligands. The Lewis base ligands chosen were (i) 2,2′-bipyridine and (ii) triphenyl phosphine and carbonyl together. The molecular structures of two of the complexes were studied by X-ray crystallography. The effect of these two different set of ligands as well as the Schiff base ligands on the fluorescence spectra of the complexes in organic solvent were compared.
Graphical abstractThe synthesis of six new ruthenium(II) complexes with pyrene-appended Schiff bases were done and their coordination behavior and photophysical properties were studied. Two different sets of Lewis base ligands (i) 2,2′-bipyridine and (ii) triphenyl phosphine and carbonyl together were chosen to generate two well known ruthenium(II) precursor. Schiff base ligands were reacted with these ruthenium(II) precursor to generate six ruthenium(II) complexes. The molecular structures of two of the complexes were studied by X-ray crystallography. The effect of these two different set of ligands as well as the Schiff base ligands on the fluorescence spectra of the complexes were studied in details.Figure optionsDownload full-size imageDownload as PowerPoint slide
