摘要：

The degree of circular polarization in the absorption of light by films of a chiral polyfluorene derivative was found to depend strongly on the thickness of the film. This indicates that the exceptionally high dissymmetry ratios observed for these films originate on a nanoscopic level and were related to the long range correlation in the polymer chain orientation induced by annealing the film in its liquid crystalline phase at high temperature.
