Characterization of thin films of regioregular poly(alkylthiophene)s bearing optically active substituents.

The spectroscopic behavior of thin films of regio regular poly(alkylthiophene)s bearing an optically active alkyl group has been investigated in the solid state under different sample preparation procedures. The experimental results are interpreted in terms of influence of the side-chain substituents on the extent of planarity of the polymeric chains and the formation of optically active chiral aggregates.
