Abstract

Electropolymerization of π-conjugated polymers is considered as an alternative method for depositing and patterning charge injection, transport, and luminescent layers in organic electronic devices. In this study, a series of novel poly(fluoren-9,9-diyl-alf-alkan-α,ω-diyl) polymers with increasing alkyl spacer lengths were synthesized and used as precursors for the deposition of conjugated polymers formed by the oxidative coupling of the fluorene units. The precursor polymers and their conjugated polymer network were characterized in solution and in film form, and their charge-transport characteristics were investigated by fabricating electroluminescent polymer light emitting diode (PLED) devices. Interesting charge carrier transport properties based on thickness and co-deposition with another precursor polymer gives the potential for optimized solid-state device performance and film processing conditions. Finally, a "two-pixel" prototype PLED was demonstrated using a sequential electrochemical co-deposition method with poly-(vinylcarbazole) (PVK).
