RESPONSE OF A HYDROGEN-BONDED LIQUID-CRYSTAL TO AN APPLIED ELECTRIC-FIELD ACCELERATED BY A POLY(GAMMA-BENZYL L-GLUTAMATE) CHEMICAL-REACTIONALIGNMENT FILM

Poly(gamma-benzyl L-glutamate) (PBLG) was bonded covalently to a flat substrate, and it formed an aligned dipole layer (PBLG-CRA film). Usin g the PBLG-CRA film as an orienting film for a nematic hydrogen-bonded liquid crystalline complex, 60BA-9Py (formed from 4-(hexyloxy)benzoic acid (60BB) and 4-nonylpyridine (9Py)), complexes, not only in the vi cinity of the CRA film but also in the bulk layer, were able to respon d more rapidly to an applied electric field when using a rubbed polyim ide film, and they became responsive at frequencies in the MHz region. We conclude that the PBLG-CRA film has a dynamic orienting force, tha t dipole-dipole interaction takes place between the interfacial 60BA-9 Py complexes and the PBLG molecules, and that the movement of the inte rfacial 60BA-9Py complexes is smoothly transferred to the bulk layer b ecause the electric state of the complex 60BA-9Py in the bulk changes under the influence of the CRA film.
