A novel homologous series of 11 ester derivatives has been synthesized and evaluated for mesogenic behaviour. The methoxy to butyloxy homologues are nonmesomorphic, whereas the pentyloxy to hexadecyloxy derivatives are enantiotropically mesomorphic in character. The hexyloxy to dodecyloxy homologues exhibit smectogenic and nematogenic both character but pentyloxy, tetradecyloxy and hexadecyloxy homologues exhibit only nematogenic character .An odd–even effect is not observed N-I transition curves. The average smectic and nematic thermal stabilities are 194.5 ºC and 197.1ºC, respectively. Smectogenic phase lengths vary from 17 ºC(C12) to29 ºC(C8) and the nematogenic phase lengths vary from 10 ºC(C16) to 27 ºC(C6) . The series is predominantly nematogenic and partly smectogenic with considerable mesophase length and a middle-ordered melting type. The liquid crystal properties of the novel series are compared with other structurally similar Series. The texture of the nematic phase is a threaded or Schlieren type, and that of smectic phase shows the smectic A type as determined by optical polarizing microscopy. Analytical data support the molecular structures in all cases.
