Exhibition of Induced Mesophases in the Binary Systems Where Both the Components are Non-Mesogenic

Abstract

Binary systems of two non-mesogens exhibiting mesomorphism are rare. In the present study few binary systems of non-mesogens exhibiting smectic and/or nematic mesophases are reported. One of the components is Schiff base having terminal isopropyl group and the other component contains an ester linkage. The binary systems of non-mesogens with terminal isopropyl group having identical structures (homologues) also exhibit induced mesomorphism. Some of the binary compositions exhibit smectic phase at ambient temperature. The phase diagrams of the present study are discussed in detail and the common features emerging from the overall study are outlined.
