Abstract

We report energy transfer from polyfluorene containing binaphthyl, P(BiNDO-FO3), to the europium complex, Eu(dnm)3phen. The P(BiNDO-FO3) has an electroluminescence (EL) peak at 422 nm where as pure polyfluorene (PF) has an EL peak at 438 nm. We have doped both polymers and report energy transfer in P(BiNDO-FO3), which is not present in PF. This is due to overlap of the absorption spectrum in the Eu(dnm)3phen with the emission spectrum of the P(BiNDO-FO3) while there is no overlap with the emission spectrum of PF.
