- LOW-MELTING NEMATIC 4,4 prime -BIS-(ALKYLBENZAL)-2-CHLORO-1,4-PHENYLENEDIAMINES.
-
A series of 4,4 prime -bis(alkylbenzal)-2-chloro-1,4-phenylenediamines were prepared and their mesomorphic behavior characterized. All homologues showed nematic behavior with broad mesophases and rather low-melting points. The mesomorphic behavior is compared with that obtained from the 4,4 prime -bis-(alkoxybenzal)-1,4-phenylenediamine series and the 4,4 prime -bis-(alkoxybenzal)-2-chloro-1,4-phenylenediamine series.
