ABSTRACT:
Mixtures and light-emitting devices that incorporate such mixtures are disclosed in which a soluble phenyl-substituted poly(para-phenylene vinylene) (PPV) copolymer (“superyellow”) is used as the host light-emitting polymer and methyltrioctylammonium trifluoromethanesulfonate, an ionic liquid, is used to introduce a dilute concentration of mobile ions into the emitting polymer layer. These mixtures and devices incorporating them are able to combine some of the characteristics of polymer light emitting diodes (PLEDs) and polymer light-emitting electrochemical cells (PLECs).
