title: Directional crystallization of polymer molecules through solvent annealing on a patterned substrate.
abstract: Multi-crystalline fibers of poly (3-hexylthiophene) (P3HT) have been grown on a patterned substrate through annealing the spin-coated film in the solvent of 1,5-pentanediol at 120 °C. The large-area patterns of photoresist grating have been fabricated by interference lithography, enabling growth of crystal fibers in a length scale of centimeters. The produced organic crystal fibers were characterized by microscopic, spectroscopic, and electrical conductivity performances. Mechanisms for the crystallization processes were investigated.
