Electroluminescence from Conjugated Polymer Electrospun Nanofibers in Solution Processable Organic Light-Emitting Diodes

Nanofibers of poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(1,4-benzo-{2,1′,3}-thiadiazole)] (F8BT) blended in polystyrene (PS) or polyethylene oxide (PEO) show different diameters and morphology according to the conjugated polymer concentration. Electroluminescence from ribbonlike F8BT nanofibers, o...

description Nanofibers of poly[(9,9-dioctylfluorenyl-2,7-diyl)-alt-co-(1,4-benzo-{2,1′,3}-thiadiazole)] (F8BT) blended in polystyrene (PS) or polyethylene oxide (PEO) show different diameters and morphology according to the conjugated polymer concentration. Electroluminescence from ribbonlike F8BT nanofibers, obtained by an annealing process of the F8BT/PEO blend, is successfully obtained by applying 6 V bias. Electrical connection is achieved by incorporating the F8BT fibers of about 700 nm width and 110 nm height into a single layer organic light emitting device, whose architecture induces charge recombination on the conjugated polymer nanofibers. This simple method to electrically connect the conjugated polymer nanofibers offers a great potential for low-cost flexible nanodevice fabrication.
