Abstract
The complex Ag(I)(flavonolate)(PPh3)(2) has been prepared and characterized including the crystal structure. This compound shows in degassed solution two emission bands, a fluorescence at lambda(max) = 505 nm and a phosphorescence at lambda(max) =780 nm. Both emissions originate from lowest-energy flavonolate intraligand excited singlet and triplet states, respectively. In the presence of oxygen, ...
Abstract
The complex Ag(I)(flavonolate)(PPh3)(2) has been prepared and characterized including the crystal structure. This compound shows in degassed solution two emission bands, a fluorescence at lambda(max) = 505 nm and a phosphorescence at lambda(max) =780 nm. Both emissions originate from lowest-energy flavonolate intraligand excited singlet and triplet states, respectively. In the presence of oxygen, the phosphorescence disappears and the complex becomes light-sensitive. The flavonolate ligand undergoes a photooxidation by oxygen.
