Poly(9,9‐di‐ n ‐octylfluorene‐ alt ‐benzothiadiazole) (F8BT) nanopillars were fabricated using the template wetting method. In order to obtain nanostructures, self‐ordered nanoporous alumina has been employed as template. Environmental scanning electron microscopy (ESEM) images reveal that the resulting F8BT structures present diameters ∼225 nm and heights ∼500 nm. The influence of the template and the solvent in the photophysical properties of the F8BT structures have been studied by UV‐Vis absorption, photoluminescence and Raman spectroscopy. These polymer structures have a wide range of potential applications due to its optical and electrical properties.
