The authors report the observation in partially converted precursor-route poly(p-phenylene vinylene) (PPV) of a strong light-induced luminescence fatigue. Increasing the conversion towards the fully conjugated polymer results in a loss of the quenching effect. They discuss exciton annihilation at photoexcited charged polaronic states as a possible mechanism for this phenomenon.
