Abstract
Do the twist: The preference of large pentiptycene-pentiptycene dihedral angles and the restricted torsional relaxation for pentiptycene-derived oligo (p-phenyleneethynylene)s in a 2-methyltetrahydrofuran glass at 80 K result in a localized excited state. These results demonstrate not only the concept of torsion-induced localization of excitation but also the efficient intrachain energy hopping processes in conjugated polymers.
