N2 - For conjugated polymers with non-degenerate ground state, the excited state of a polaron is stable, and its static polarizability is negative. Then the photoinduced polarization reversion (PPR) can occur in a polymeric molecule with a polaron induced by doping. Here the PPR produced by a polaron needs only one photoexcitation; but that produced by a biexciton needs to be photoexcited twice. Therefore this Letter provides a easier way to observe the PPR in the polymers.
