A symmetric tetrathiafulvalene-base molecule (symTTF11) was newly synthesized by attaching four flexible alkyl chains at the periphery of board-shaped molecule. Phase behaviors and physical properties of symTTF11 were further investigated by the thermal, microscopic and scattering experimental techniques. Their phase structures of columnar crystalline phase and a columnar smectic LC phase were indentified. Since the assembled symTTF11 columns were well organized in the ordered layer structures over a macroscopic domain in the columnar smectic LC phase, symTTF11 showed a good charge carrier mobility, which was about two-order of magnitude faster than that in the columnar crystalline phase.
