Induced by systematic variation of the initial polymer concentration in toluene, various morphologies of aggregates including vesicles, spheres, onion-like structures, and worm-like fibers from a rod-coil-rod triblock copolymer, oligo(p-phenyleneethynylene)-polystyrene-oligo(p-phenyleneethynylene) , were observed by transmission electron microscopy.

The solution aggregation and synthesis of polystyrene-oligo(p-phenyleneethynylene) (OPE)-polystyrene triblock copolymer are studied. Variation of physicochemical interactions between the relative lengths of the blocks and the constituent blocks allow a tailoring of morphologies. The use of the solvent composition to influence chain conformations is also demonstrated. It is found that the triblock copolymer exhibits unique solvatochromatic behaviors through planarization of the conjugated backbone and aggregation-induced π-π stacking.
