Synthesis and mesomorphic properties of fluorinated Schiff's base esters containing alkyl and alkoxy end groups

Two series of fluorinated Schiff's base esters have been synthesized and characterized. Their chemical structures were identified by FTIR, 1H NMR, and elemental analysis (EA). Their mesomorphic properties were studied by polarizing optical, microscopy (PO

Liquid-Crystalline Heterocycloalkanes. III. Synthesis and Liquid-Crystalline Properties of Substituted 1,3-Dioxadecalines

Liquid-crystalline 2-substituted and 2,6-disubstituted 1,3-dioxadecalines (4-6) were synthesized by acid-catalyzed acetalization of trans-2-hydroxymethylcyclohexanol (1) or trans-4-alkyl-trans-2-hydroxymethylcyclohexanoles (2) with aldehydes 3 whereby the desired trans-isomers were formed only.The syntheses of the various aldehydes are also described.Special attention is drawn on the evolution of mesogenic properties of the title compounds 4-6 in comparison with known decalines and 1,3-dioxanes.It was found that the clearing temperatures of the synthesized 1,3-dioxadecalines are always lower than those of the corresponding decaline derivatives, due to the deformation of the decaline-ringsystem by the introduction of two oxygen-atoms.The comparison of 1,3-dioxanes and 1,3-dioxadecalines shows that the dioxadecaline ringsystem tends to suppress smectic mesophases in favour of nematics.A first example of a liquid crystalline cis-fused 1,3-dioxadecaline (8) is described, too.

Broad Nematic Phases with High Clearing Points

Unbranched 4-(4'-alkylbenzoyloxy)-, 4-(4'-methylaminobenzoyloxy)- and 4-(4'-dimethylaminobenzoyloxy)benzylidene-4''-cyanoanilines were synthesized.They show broad nematic phases with high nematic isotropic transitions.Lateral Cl-substituents decrease the
