Abstract
A high quality single-crystalline polyalkylthiophene structure can be easily prepared by the inventive method which comprises: (i) dissolving polyalkylthiophene in an organic solvent at a temperature ranging from 50 to 100° C., sequentially quenching the polyalkylthiophene solution at a temperature ranging from 25 to 40° C. and then at −5 to 15° C., to obtain a self-seeding polyalkylthiophene solution; and (ii) applying the self-seeding polyalkylthiophene solution obtained in step (i) to one surface of a nano-template having a hydrophobic supramolecule coating layer formed thereon to induce self-assembly and crystallization of polyalkylthiophene on the surface.
