Several homologous series of the 1,4-disubstituted piperazines of the general formulas 4a-l, 6a-k, 7a, b, 8a-r were synthesized.Most of the new substances are liquid crystalline.Besides nematic phases also smectic phases of the types A, B and E exist, which was proved by texture and miscibility studies.
