| Abstract | The synthesis of polymers (-Cz-C≡C-PtL2-Cz-X-)n along with the corresponding model compds. (Ph-PtL'2-C≡C-Cz)2-X-, where Cz = 3,3'-carbazole, X = nothing, Cz, or F (2,2'-fluorene), L = PBu3, and L' = PEt3 are reported. The electronic spectra (absorption, excitation, emission, and ns-transient spectra) and the photophysics of these species in 2-methyltetrahydrofuran at 298 and 77 K are presented. Evidence for singlet electron and triplet energy transfer from the Cz chromophore to the F moiety are provided and discussed. The rate for electron transfer is very fast (>4 × 1011 s-1), whereas that for triplet-triplet energy transfer is much slower (≈103 s-1). This work represents a very rare example of studies that address electronic communication in the backbone of a conjugated organometallic polymer. [on SciFinder(R)] |
