Preserved Fulltext
Molecular orientations by shear stress and magnetic field were carried out to obtain a uniaxial, low-bandgap, amphotropic liquid crystalline (LC) -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 orientation of a lyotropic polymer LC under magnetic field.
