| Abstract | Highly crystalline, well-defined nanowires of a donor-acceptor (D-A) conjugated polymer based on bithiazole-thiazolothiazole (PTz) were successfully prepared by a facile solution self-assembly method. In PTz nanowires, polymer chains align along the long axis of the nanowires forming lamellar structures with close pi-stacking perpendicular to the long axis of the nanowires. The nanowires possess a single crystal structure with orthorhombic crystal unit cell in which the lattice parameters are a approximate to 21.05 angstrom, b approximate to 6.94 angstrom, and c approximate to 4.64 angstrom. The intrinsic charge transport property of PTz was characterized by using its single crystal nanowires in field-effect transistors with a mobility up to 0.46 cm(2) V-1 s(-1). As an example of PTz single crystal nanowires in optoelectronic application, phototransistors of PTz nanowires exhibited a photoresponsivity up to 2531 A W-1 and a photosensitivity up to 1.7 x 10(4). |
