Exciton dynamics in π-conjugated polymer systems

Abstract:

Experimentally, it is observed that upon photoexcitation, conjugated polymers undergo sub-picosecond coupled exciton-phonon dynamics, in which the nuclei distort to stabilise the new electronic state. Previously, such relaxation dynamics of highly excited electronic states of poly(p-phenylenevinylene) have been modelled using Ehrenfest dynamics. Rather than the system relaxing onto a single emissive chromophore as physically expected, the dynamics were seen to bifurcate into a quantum supe...
