An inside job : By using single‐molecule spectroscopy (SMS) several effects of solvent vapor induced annealing (SVA) were studied directly on single conjugated polymers, e.g.: SVA‐induced translocations, folding/unfolding dynamics, and changes in the morphological order. It is shown that single chains can be trapped by spin‐coating in a disordered conformation and subsequent SVA leads to an equilibrated, highly ordered conformation (see picture).
