Circular Dichroism and Circular Polarization of Photoluminescence of Highly Ordered Poly{3,4-di[(<i>S</i>)-2-methylbutoxy]thiophene}

Abstract

Conformationally disordered poly{3,4-di[(S)-2-methylbutoxy]thiophene} is prepd. via monomer polymn. by anhyd. FeCl3. Optically active ordered polymer is prepd. by cooling of the polymer to -30 Deg. In the aggregated phases a splitting of the excited state into two exciton levels occurs
