Abstract
The ladder-type Poly(paraphenylene) m-LPPP is a very suitable conjugat ed polymer for application in electroluminescence (EL) devices. We rep ort on the dependence of the photoluminescence on applied electric fie lds and discuss the observed quenching effects in terms of current ind uced quenching and field induced quenching of the emitting species. Th e field dependent PL measurements were used to quantify the field indu ced dissociation of the emitting species and to obtain an estimate of the binding energy of singlet excitons in the m-LPPP polymer.
