Patent ID: 7892355

Claim:
A method for preparing a single-crystalline polyalkylthiophene structure, which comprises: (i) (i-a) dissolving polyalkylthiophene in an organic solvent at a temperature ranging from 50 to 100° C., quenching the polyalkylthiophene solution at a temperature ranging from 25 to 40° C. and keeping the quenched solution at that temperature for at least 1 hr, and (i-b) further quenching the solution obtained in step (i-a) at a temperature ranging from −5 to 15° C., followed by stirring at that temperature for a period of 10 to 48 hrs, 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 of polyalkylthiophene on the surface and allowing the growth of polyalkylthiophene crystals thereon.
