520 a In order to study the effects of the substituted groups on the properties of the complexes, a series of rhenium ( I ) 2, 2'-bipyridyl complexes [fac- (4, 4'-di-COOEt-bpy) Re (CO)(3) (X-pyridine) PF6], where bpy is 2,2'-bipyridine and X is 4-methyl, 3-hydroxy, 4-hydroxy, 4-amino, or H, were synthesized with a yield more than 90%, and characterized by H-1 NMR, C-13 NMR, 2D-NMR (H-1-H-1 COSY, HMBC, HSQC), ESI-MS and HRMS. The delta(H) values on the X-pyridine ring were shifted to up-field in H-1 NMR and the MLCT absorbance maxima were red-shifted as the X groups became more electron-donating from H to 4-methyl, 4-hydroxy or 4-amino. The ESI-MS and FIRMS showed the mono-charged peaks and their isotopic peaks of the complexes. The absorption maximum of id(X=4-amino) is 20 nm longer than that of 1e(X=H). It might be used to broaden the absorption range of solar cells.
