Abstract

The role played by triplet excitons in polymer-based LEDs can be analysed by examining the behavior of the excitons in host polymers in a variety of host–guest polymer blend systems (the guest is a porphyrin such as that shown in the Figure) reported here. Charge and energy transfer at heterojunctions in OLEDs depends on these excitons, so an improved understanding of these processes should enable device performance to be improved.
