Tuning 'de Vries-like' properties in binary mixtures of liquid crystals with different molecular lengths

Smectic liquid crystals with 'de Vries-like' properties are characterized by a maximum layer contraction of ≤1% upon transition from the orthogonal SmA phase to the tilted SmC phase. We show that binary mixtures of 'de Vries-like' and conventional SmC mesogens with a molecular length ratio of 1.34 undergo a SmA-SmC phase transition with a maximum layer contraction ranging from 1.0 to 1.9% depending on the mixture composition.

Template-directed synthesis of symmetric as well as unsymmetric macrocycles from rigid or flexible building blocks

'Arc'-shaped oligophenyl derivatives with terminal alkene moieties can be used to form macrocycles by 'dimerization' through ring-closing metathesis. Hereby the introduction of templates connecting the two building blocks favors the dimerization over oligomerization or polymerization reactions. Attachment of the template through imine formation allows the removal of the template simultaneous to the reduction of the double bonds formed during ring-closing metathesis. Unsymmetric macrocyles can be obtained either by successive attachment of different 'arc'-shaped molecules to the template or by direct imine connection of two different ring precursors. In the latter case, the imine unit cannot be cleaved in the case of the investigated examples but 'figure-8'-shaped macrobicycles are obtained. The studied template-directed macrocyclization depends on the one hand on the preorganization of the building blocks, and on the other on their flexibility. Georg Thieme Verlag Stuttgart.

Insect Juvenile Hormone Analogues: Part VII - Synthesis of Long Chain Aromatic Ethers & Nitrogen Analogues

Syntheses of various aromatic ethers of undecenyl bromide and thio ethers of undecenyl and undecanyl bromides with 2-benzothiazolethiol are described.The preparation of a few amides and their corresponding amines from undecenoic acid and different aromatic amines and benzyl amine are also reported.The bromo derivatives of a few amides have also been prepared.These compounds have been tested on common Indian red cotton bug for their juvenile hormone activity.
