Mesomorphic Properties of Stucture Related Ester Homologous Compounds :P-(P’-N-Alkoxy Benzoyloxy) Ter- Butyl Cinnamates.

Authors(2) :-Chauhan M. L., Patel B.K

A novel homologous series of p-(p’-n-Alkoxy Benzoloxy) ter-Butyl Cinnamates was synthesized and studied for mesophase behavior dependence on molecularstructure. The nematogenic mesophase is exhibited from the Pentyloxy to the last member hexadecyloxy derivative andthe 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 mesophaseis of a focal conic fan of the type A or C. Mesomorphic properties of the present novelhomologous 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 partlynematogenic and smectogenic with considerable mesophase length. It is a middle ordered melting type series, whose relative group efficiency order for nematic derived.
