Abstract:

Time-resolved Fourier transform IR (FT-IR) polarization spectroscopy was employed to study the elec.-field-induced reorientation of nematic p-cyanophenyl-p-n-heptylbenzoate (7CPB) in the bulk of the cell and near (within 1 mm) the surface of the electrodes. The initial orientation of 7CPB on the germanium electrodes was varied in order to obtain information concerning the behavior of the liq. cryst. mols. in the boundary region. Model systems contg. the 7CPB on rubbed polyimide and poly(vinyl alc.), non-rubbed polyimide and poly(vinyl alc.), and blank germanium were prepd. and investigated.
