Abstract :
Near steady state photoinduced absorption (PIA) studies on soluble poly(p-phenylene vinylene) (PPV) and poly(p-phenylene ethynylene) (PPE) derivatives in various solvents reveals that the principal metastable photoexcitation is a triplet state. In contrast to poly(3-alkylthiophene) solutions, no charged photoexcitations are found in the PPV or PPE solutions.
