We present the synthesis and the characterization of a series of conjugated D-A copolymers, where the molecular structure, in which the changes of dipole moments by photoexcitation facilitate the electronic transitions. The dynamics of the PL process for the PFeBT suggests a model where two types of acceptor groups might be present, which would be responsible by the biexponential decays. These two decays are not related to interlumophore interactions but with lumophores in relaxed and unrelaxed forms. The dynamics of the PL process for the others polymers as underway, as well as the photovoltaic characterization.
