The synthesis and properties of an isothianaphthene-based liquid crystal (LC) π-conjugated polymer are reported. The polymer showed amphotropic LC character having both thermotropic and lyotropic liquid crystallinities with macroscopic LC fractal structure. The optical bandgap is 2.0 eV accompanied by good electroactivity.
