Polaron stability in semiconducting polymer neat films

Chem. Commun. - 3 hours 42 min ago

Chem. Commun., 2014, 50,14425-14428
DOI: 10.1039/C4CC06193D, CommunicationDaniel Beatrup, Jessica Wade, Laure Biniek, Hugo Bronstein, Michael Hurhangee, Ji-Seon Kim, Iain McCulloch, James R. Durrant
We describe a spectroelectrochemical approach to accelerated electrochemical stability studies of conjugated polymers under oxidative stress. The polaron stabilities of alternating copolymers based on (i) thiophene and thiazole, namely PTTz, and (ii) bithiophene and thiazole, namely PTTTz, are compared in neat films with that of P3HT. P3HT is found to be the most stable whilst PTTz is found to be the least stable.
