Tuning the solidification of the crystallizable solvent naphthalene, well-patterned conjugated polymer poly(phenyleneethynylene) (PPE) films with well-defined nanostructures of 0D nanodots, 1D lamellas, and 2D texture nanostructures have been prepared by several strategies. The nanostructures have been characterized and the formation mechanisms for the morphologies have been discussed.
