Abstract
The challenging synthesis of semiperfluoroalkyl polyfluorenes and characterization of their electro-optical properties has been reported. Solutions of conjugated polymers can be dispensed onto the desired area by inkjet printing or screen printing, or form films on regions where a sacrificial photoresist material defines the target. Optical properties of the polyfluorenes, including absorption maxima of the UV vis spectra and photoluminescence are summarized. The EL characteristics areinestigated in a device structure of ITO PEDOT:PSS light-emitting polymer CsF Al. Their optical and EL properties were evaluated, exhibiting distinctive characteristics from their nonfluorinated analogues. Good..
