Abstract

Molecular orientations by shear stress and magnetic field were carried out to obtain a uniaxial, low-bandgap, amphotropic liquid-crystalline (LC) π-conjugated polymer. Orientation of a thick polymer film shows orientation along the shear stress, but a thin sample produced by a spatula drawing on a glass substrate produces LC band structure with a chevron pattern. Furthermore, we report the orientation of a lyotropic LC polymer under magnetic field.
