High aspect ratio, luminescent poly(9,9-dioctylfluorene) nanowires are synthesized by template wetting. Optical spectroscopic characterization indicates the formation of a significant fraction of the polymer β-phase. The results indicate that the wires essentially act as self-doped 1D nanostructures in which the PFO β-phase dominates the luminescence behavior following optical, electrochemical or electrical excitation.
