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).
