Article abstract of DOI:10.1080/00268948208071025

Three homologous series, having a lateral substituent and different end groups have been synthesized. Series (A) is non-mesogenic while series (B) and (C) exhibit only nematic mesophase. The thermal stabilities of series (B) and (C) are much more lowered compared with the corresponding unsubstituted homologous series. Generally the introduction of a lateral substituent renders the system low melting, and the mesomorphic-isotropic transition temperatures are also lowered. However, in the present study, introduction of a bulky methoxy group as a lateral substituent lowers the mesomorphic-isotropic transition temperatures to a great extent but the melting points are not much depressed.
