Aromatic 1H and 13C assignments of regioregular oligooctylthiophenes NMR study of the “end of chain” protons of a HT polyoctylthiophene.

A regioregular HT sexioctylthiophene was characterized by 1H NMR in CDCl3 and THF-d8 and 13C NMR in CDCl3. The data of the 1H NMR spectra were used to study the “end of chain” thiophenes of a regioregular HT polyoctylthiophene in CDCl3 and THF-d8.
