Highlights► In this work we study of the molecular structure of P3OT and P3HT and the phase transitions. ► From the calorimetric diagrams we obtain the melting and crystallization temperatures. ► We identify a low temperature calorimetric glass transition. ► GIXRD shows an increase of the crystallinity for the P3HT and not in the P3OT with the annealing. ► Interdigitation of the side chain is produced for the P3HT and not in the P3OT.
