Luminescence of [Re I (L–L)(CO) 3 Cl] with L–L = lumazine and folic acid

Zusammenfassung

The complexes [Re-I(L-L)(CO)(3)Cl] with L-L = lumazine and folic acid were prepared and their electronic spectra were measured. The free ligands L-L, as well as both complexes, show an emission which is attributed to the fluorescence of L-L. This luminescence is apparently facilitated by excited state proton transfer.
