A new mesogenic homologous series with broken alkoxy chain at the terminus of long polarizable molecules having following general formula have been synthesized. RO-C6H4-COO-C6H4-CH=N-C 6H4-COOCH2CH2OCH2CH 3 Where, R=-CnH2n+1; n=1 to 8, 10, 12, 14 and 16. All the members exhibit enantiotropic mesomorphism. Methoxy derivative is purely nematogenic. Ethoxy to n-hexyloxy derivatives exhibit enantiotropic smectic-A as well as nematic mesophases. n-Heptyloxy to n-hexadecyloxy derivatives exhibit only enantiotropic smectic A mesophases. The thermal stabilities and the commencement of smectic phase of the present series are compared with those of other structurally related series.
