Abstract
We report on experiments that prove the occurrence of singlet exciton quenching by photogenerated geminate pairs of charges in a ladder-type conjugated polymer—methylsubstituted poly(para-phenylene). The pump-probe technique was used in measurements of the quenching effect. The observed kinetics of the quenching effect correlates with the time dependence of the geminate pair concentration as revealed by the complementary study of the kinetics of delayed fluorescence.Keywords
