Abstract

The search for the hexatic phases such as smectic-F and G in N-(p-n-alkoxybenzylidene)-p-n-alkyl anilines, nO.m s series has revealed that a number of higher homologues of this series exhibit a direct isotropic liquid to hexatic smectic-F and G phases in addition to the lone compound hither to known in nO.m series viz., 10O.14. The compounds of the 12O.m series (with m = 12, 14 and 16), 11O.12 and nO.14 series (with n = 10 to 16) exhibit a direct smectic-F, while the compound 18O. 14 exhibits a direct smectic-G transition from isotropic liquid.
