논문초록 Microstructures of conjugated-polymers in condensed-phase have shown to play important roles on governing the performance of polymer-based optoelectronics. We prepared highly-ordered crystalline poly(3-hexylthiophene) particle (P3HT-CP), made with regioregular P3HT (regioregularity>99%) by slow antisolvent diffusion method. Various particle characterization data, including SEM and TEM and x-ray diffraction analysis verified the high degree of crystalline formation, revealing continuous crystalline domains extending over 100s nm scale.[1] Electronic absorption spectroscopy and excited-state dynamics based on fluorescence and ultrafast transient absorption spectroscopy for the P3HT-CP will be discussed. These microscopic and optical spectroscopic results suggest enhanced crystallinity in P3HT-CP, which could be a model system to understand exciton dynamics in polymer crystalline domains and the role of polymer microstructures.
