摘要：

Regioregular poly(3-hexylthiophene) has been successfully incorporated into a novel amphiphilic block copolymer. The amphiphilic nature of poly(3-hexylthiophene)-block-poly(acrylic acid) has been investigated using spectroscopic methods and has yielded solvatochromic behavior in several solvents of varying polarity. Evidence suggests that a supramolecular, long range ordering of block copolymer occurs in polar solvents, resulting in the formation of aggregates. Despite relatively large amounts of non-conductive blocks, the poly(3-hexylthiophene) diblock copolymer yields a high conductivity of 1 S. cm and atomic force microscopy shows the formation of a highly organized nano-fibrilar morphology in the solid state.
