- The electrospray ionization mass spectrometry (ESI-MS) of a series of rhenium(I) bipyridyl complexes [(4,4'-(COOEt)(2)-bPY)Re(CO)(3)RPF6], where bpy is 2,2'-bipyridine and R is pyridine, 4-methylpyridine, 4-hydroxypyridine, 4-aminopyridine or 10-(4-picolyl)phenothiazine (py-PTZ) was studied. The dissociation of the ligands (R) forms the fragment of [(4, 4'-( COOEt)(2)-bpy) Re (CO)3](+) at different voltages of in-source collision induced dissociation (CID). The dissociation tendency is in an order: pyridine > 4-methylpyridine > 4-hydroxypyridine > 4-aminopyridine > py-PTZ. It might be used to deduce the stability of these complexes when they are used as photosensitizers in solar cells.

Studies on a series of rhenium(I) bipyridyl photosensitive dyes

Journal article (peer-reviewed)abstract
- A series of rhemium(I) 2,2'-bipyridyl complexes [fac-(4,4'-di-COOEt-bpy)Re(CO)(3)(Xpy)PF6] (bpy = 2, 2'-bipyridine; py = pyridine; X = 3-methyl, 3-hydroxy, 3-amino, H) were synthesized. Their electrochemical properties, ground state electronic spectra and emission spectra were studied in acetonitrile. As the X group became more electron donating from H to 3-methyl, 3-hydroxy or 3-amino, the Re(II/I) oxidation potentials declined, the MLCT absorption maximum of the complex was changed little, the emission maximum blue-shifted, and the emission intensity and the fluorescence lifetime were decreased.
