Abstract

A novel homologous series of p-(p’-n-Alkoxy Benzoloxy) ter-Butyl Cinnamates was synthesized and studied for mesophase behavior dependence on molecular  structure. The nematogenic mesophase is exhibited from the Pentyloxy  to the last member hexadecyloxy derivative and  the smectogenic mesophase from the pentyloxy  to the tetradecyloxy member of the series. The nematic mesophase is of a threaded or Schlieren type, and the smectic mesophase is of a focal conic fan of the type A or C. Mesomorphic properties of the present novel homologous series are compared with other structurally similar homologous series. The average smectic and nematic thermal stabilities are 172.33 ºC and 202.14 ºC, respectively. Smectogenic phase lengths vary from 22 ºC (C14)  to 58 ºC (C8)  and the nematogenic phase lengths vary from 10 ºC (C16)  to     50 ºC (C5). The series is  partly nematogenic and smectogenic with considerable mesophase length. It is a middle ordered melting type series, whose relative group efficiency order for nematic derived
