Synthesis, crystal structure, photoluminescence and photochemistry of bis(triphenylphosphine)silver(I) flavonolate

Vogler, Arnd ; Hischa, Birgit


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, ...
