Effect of Counterions on the Interactions of Charged Oligothiophenes
Effect of Counterions on the Interactions of Charged Oligothiophenes
The functionality of conjugated polymer systems often relies on oxidations or reductions, in most cases mediated by the presence of counterions. The effect that the common counterion hexafluorophosphate (PF6-) has on the intermolecular interactions between charged oligothiophenes is investigated here using ab initio quantum chemistry methods. Counterions are explicitly included …
