Ultraviolet absorption and Circular Dichroism spectra in the region 300- 700 nm for highly regioregular samples of Poly{3[(S)-2-methylbutyl]- thiophene} are reported for solutions in good and poor solvents, at variable temperature, and for films in various conditions. In the latter case novel CD data up to the melting temperature provide some hints for the self-assembling process towards supramolecular organization.

Abstract
Ultraviolet absorption and Circular Dichroism spectra in the region 300- 700 nm for highly regioregular samples of Poly{3[(S)-2-methylbutyl]- thiophene} are reported for solutions in good and poor solvents, at variable temperature, and for films in various conditions. In the latter case novel CD data up to the melting temperature provide some hints for the self-assembling process towards supramolecular organization. UV- visible and CD data are also reported on the related polymer Poly{3,4-di [(S)-2-methylbutyl]-thiophene}.File in questo prodotto:
