Spontaneous Formation of Left- and Right-Handed Cholesterically Ordered Domains in an Enantiopure Chiral Polyfluorene Film. Savoini, M., Biagioni, P., Meskers, S. C. J., Duò, L., Hecht, B., & Finazzi, M. J. Phys. Chem. Lett., 2(12):1359-1362, 06, 2011.

Thermally annealed chiral polyfluorene films are studied by circular differential optical microscopy. We observe the presence of micrometer-sized domains displaying circular dichroism of opposite sign. Our findings suggest the spontaneous occurrence of left- and right-handed cholesterically ordered domains from an enantiopure precursor. The role of enantiopure stereo centers in the side chains of the polymer is to lower the energy of the left-handed cholesteric domains with respect to the right-handed ones.
