Photoinduced luminescence of fac-[Re (CO) 3 (phen)(stpy)]+ in CH3CN and PMMA
The photophysical and photochemical behavior of the fac-[Re (CO) 3 (phen)(stpy)]+
complex, where phen= 1, 10-phenanthroline and stpy= 4-styrylpyridine, in acetonitrile
solution and in poly (methyl methacrylate), PMMA, polymer film has been studied. Under
irradiation, the complex exhibits trans–cis photoassisted isomerization of the coordinated
ligand stpy. The apparent quantum yields determined by absorption changes in acetonitrile
are Φ313= 0.35±0.02, Φ334= 0.36±0.02 and Φ365= 0.31±0.02. The 1H NMR spectra and …
