Anions and neutral radicals of trialkoxy substituted trioxotriangulene (TOT) derivatives (TOT(O-n-CnH2n+1)) have been synthesized and their temperature dependent polarizationmicroscopy and DSC measurement suggested that they becomes thermotropic liquid crystal. Furthermore, anion of tris(3,4,5-tri(dodecyloxy)phenyl) substituted TOT displays discotic columnar liquid crystalline phase. The liquid crystalline organic molecules developed in this research in which electronic spin and electronic charge is delocalized widely on its molecular backbone had never been reported. The accumulation of the knowledge about this kind of novel organic molecular systems should leads the first step for the realization of the liquid crystal material that could quickly respond to the external stimuli and could be applied to 3D imaging. The result of this research could also contribute to the development of the light functional materials for organic thin layer solar cells and multifunctional materials in which light, electricity, and magnetism are working together, and it is expected to construct a base of new industry in the future.
