Binary systems of non-mesogens with naphthalene derivatives

Binary mixtures with both the components are non-mesogenic becomes an interesting and enlighten feature when they exhibit mesomorphism at ambient temperature. In the present study, we report five binary systems where two non-mesogenes exhibit smectic and/or nematic mesophases at ambient temperature over a certain range of concentration. All the binary systems contain one non-mesogenic naphthalene derivative. The study provides many binary systems of non-mesogens which exhibit mesophases at ambient temperatures. The terminal nitro chain is found to be responsible for the induction of both the nematogenic and smectogenic tendency in the present investigation of binary systems with two ‘compatible' component.

Study of mixed mesomorphism in binary systems of azo-ester mesogens with structurally dissimilar nonmesogenic as well as mesogenic ester homologues

We have studied mixed mesomorphism in four binary systems comprising two azo-ester mesogens, viz. 4-(4′-n-alkoxybenzoyloxy)3-methylphenyl azo-2″ and 4″-dimethylbenzenes (where n-alkoxy is n-butoxy or n-hexyloxy), and two ester nonmesogenic and mesogenic components, viz. 4-nitrophenyl-4′-n-alkoxybenzoates (where n-alkoxy is n-butoxy or n-hexyloxy). All the four binary systems are mesogenic in nature, showing nematic phase with threaded/marble texture. The phase diagrams of the binary systems are plotted and eutectic transition temperatures and maximum mesophase ranges of the nematic mesophase in all the systems are determined.

Exhibition of induced mesophases in the binary systems where both the components are non-mesogenic

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.
