1 Poly(3-hexylthiophene)
Structural Dynamics in Conducting Polymers Aaron M. Massari, Department of Chemistry, University of Minnesota - Twin Cities, Minneapois, MN 55455 In this work we seek to measure the structural dynamics of conducting and semiconducting polymers that have potential applications as lightweight energy storage materials. Our approach involves embedding and IR-active chromophore into a polymer film to serve as a reporter of the local chemical dynamics. The methodology that we use to extract these dynamics is 2D-IR Vibrational Echo Spectroscopy (VES) Time-dependent perturbations by solvent and/or surrounding molecules (polymers) cause frequency shifts in the “reporter” molecule… “reporter” P3HT + During the solvent vapor annealing process, the charge carrier mobility of P3HT increases by 30%, and the dynamics in these data suggest that ring torsional motions are damped out.
