Abstract
We have carried out energy transfer studies of 5,5'-(2-dithienyl)-2,2'-bipy ridazine Eu+3 (DTBPZ-Eu) complexes. Tuning the excitation to the oligomer a bsorption band, we have obtained characteristic Eu+3 photoluminescence. Lon g lived excitations that are photogenerated in the pure oligomer are absent in the complex, indicating a fast energy transfer process.
