[Abstract]

Herein is a description of the mass production of poly(9,9-dioctylfluorene-co-benthiadiazole) (F8BT) and poly(9,9-dioctylfluorene) (PFO) nanowires (NWs) using a melt-assisted wetting method with an anodic alumina membrane. The conjugated polymer NWs had a uniform shape (D = 250∼300 nm/L = 10∼30 μm) and a defect-free smooth surface. Optical properties were investigated by UV-vis, photoluminescent spectroscope, and fluorescent optical microscope. Individual F8BT and PFO NWs had a bright yellow (λ = 541 nm) and blue (λ = 442 nm) luminescence, respectively, under UV light irradiation.
