Poly (3-alkylthiophenes) (P3ATs) particularly poly (3-hexylthiophene) (P3HT) have vigorous tendency to crystallize into the ordered morphologies, thereby reflect the efficient electrical and optical characteristics. Here, the remarkable crystalline structures of P3ATs comprising single crystals, nanofibers, nano/microwires, nanoribbons, micelles, nanowhiskers, thin films, spherulites, etc. are thoroughly reviewed. In each category, the principle aspects like preparation methodologies (e.g., self-seeding, shearing, electrospinning, self-organization, epitaxial solidification, etc.), micro/nanostructures, orientation and optical properties are meticulously brought into consideration. Applications of the ordered P3AT structures in solar cells, organic field-effect transistors, and sensors as well as the theoretical studies are also highlighted. Furthermore, the polymorphism, sol-gel, nanoparticles, liquid crystalline morphology, and two-dimensional sheets are reviewed.
