Self-Assembled Columnar Structures of Swallow-ShapedTetrathiafulvalence-Based Molecules |
초록 |
A series of swallow-shaped tetrathiafulvalence-based liquid crystal (LC) molecules (a-6TTFn) was designed and synthesized. Major phase transitions were studied with combined techniques of differential scanning calorimetry (DSC), one-dimensional (1D) wide-angle X-ray diffraction (WAXD) and solid-state carbon-13 (13C) nuclear magnetic resonance (NMR) experiments. The structure, molecular packing symmetry, and morphology of a-6TTF12 in different phases were identified using 2D WAXD together with selected area electron diffraction (SAED). Morphological observations utilizing cross-polarized optical microscopy (POM) on the micrometer length scale validated the phases transitions and molecular orientation in the macroscopically oriented film. |
