The degree of circular polarization in the absorption of light by a thermally annealed film of chirally substituted polyfluorene depends strongly on the film thickness. This indicates that the exceptionally high dissymmetry ratios observed for these films originate on a nanoscopic level and are related to the long‐range correlation in the polymer chain orientation. Circular polarizations (see Figure) of up to 50 % can be reached.
