Abstract
The electronic structure and exciton dynamics of the molecules and polymers that form the active layer in organic electronic devices is governed by the electronic coupling between molecules. Molecules and polymers may become kinetically trapped during spin-coating. Thermal annealing can change these conformations, dramatically changing the exciton dynamics and thus the suitability of the material for electronic devices. In this work, a single-shot transient absorption spectroscopy technique is used that can measure the exciton dynamics of organic semiconducting systems during thermal annealing.
