Abstract

The DF and PLDMR of triplet exciton and polaron dynamics in (pi) -conjugated materials and devices is reviewed, and the significance of various processes involving these long-lived excitations is considered. These include the generation of singlet excitons by triplet-triplet annihilation, which leads to DF, and nonradiative quenching of such singlets by polarons or triplet excitons. The clear differences between the roles of these processes in (pi) -conjugated polymers vs small molecules and their implications for organic light emitting devices are discussed.
