To regulate the molecular arrangement and morphology from the nano to micro length scale, the novel achiral molecule (abbreviated as AT1M) containing the tetrathiafulvalene (TTF) was synthesized and identified. From the 2D WAXD techniques, uniaxially oriented AT1M is identified with the ordered monoclinic crystal. Furthermore, the combination of SAED, TEM, AFM techniques observed formation of the scrolled and helical ribbons as well as flat ribbons from achiral AT1M compounds. The scrolled and helical structures are originated by imbalanced surface stresses resulting from the molecular packing in the monoclinic cell of the crystalline phase. The electrochemical and optical properties of the AT1M compound are also investigated using CV and UV-Vis spectroscopy. This work was mainly supported by the Basic Science Research Program, and BK21 PLUS Program, Korea. |
