Outline of Final Research Achievements

In this study, we have clarified the crystal structures of dialkylated quterthiophenes (Cn-4T, n= 0, 4, 6, 8, 10, 12).) using in situ 2-dimensional grazing-incidence X-ray diffraction (2D-GIXD) during thin-film growth, and the effects of alkyl-chain length on the crystal growth mode, structure and transport properties are elucidated.
