Results of triplet-triplet energy transfer from biacetyl to OPVs and OPV triplet state quenching by 1, 4-diazabicyclo[2.2.2] octane (DABCO) suggested that triplet state of oligophenylenevinylenes(OPVs) directly takes part in their photooxidative degradation instead of just generating singlet oxygen.
