Two dimensional hierarchical architectures fabricated by the self-assembly of poly(3-hexylthiophene)-b-polyethylene glycol

2D multi-layered hierarchical architectures, ball-like micelles, flower-like aggregates and nanoribbons were fabricated by the self-assembly of poly(3-hexylthiophene)(P3HT)- b -polyethylene glycol with a short P3HT chain in alcohol solvents.
