Abstract

Several homologues of the 4,4'-bis-(alkoxybenzal)-2-chloro-1,4-phenylene series were synthesized and their mesomorphic behavior characterized. Furthermore a new series of liquid crystalline compounds, 4,4 1 -bis­ (alkylbenzal)-chloro-l,4-phenylenediamines, have been synthesized and the mesomorphic behavior characterized up to the c carbon chain length. All homologues showed nematic behavior with broad mesophases and particularly low melting points.
