Multiple self-assembled nanostructures from an oligo(p-phenyleneethynylene) containing rod-coil-rod triblock copolymer

摘要

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-phenyleneethyny-lene),were observed by transmission electron microscopy.
