Tetraphenylenes 2 with eight peripheral gallic esters were prepared in two steps from octamethoxytetraphenylene 1 in 19–72% yield. Investigation of the mesomorphic properties of 2 by DSC, POM and X-ray diffraction revealed that derivatives 2a–d w

The self-assembly of amphiphilic molecules in aqueous solution into lyotropic liquid crystals (LCs), characterised by soft yet long-range ordered nanoscale structures, constitutes a fascinating phenomenon at the heart of soft matter science which can

A series of 2‐(4‐n‐alkylphenyl)indenes (3) with different alkyl substituents (CH3 to C10H21) were synthesized and systematically characterized using differential scanning calorimetry, polarizing optical microscopy and X‐ray diffraction compar

Die meisten Menschen verbinden mit dem Begriff Flussigkristalle sofort die Displays von Laptop-Computern, Mobiltelefonen, Digitalkameras und anderen elektronischen Geraten. Im Unterschied zu ihren stabchenformigen (calamitischen) Verwandten, die erst

We report the synthesis and liquid crystalline properties of novel ester‐substituted tetraphenylenes obtained from octamethoxytetraphenylene by demethylation and esterification. The target compounds display focal‐conic textures typical for column

We report the synthesis and liquid crystalline properties of novel mesogenic octaalkyloxytetraphenylenes. Starting from 4-bromoveratrol, the saddle-shaped target tetraphenylenes were obtained in fi...

Rather uncommon but pronounced odd-even effects in the clearing temperatures of liquid crystals are found for three new homologous series of discotic tetraphenylenes [figure: see text]. Detailed similarities to the well-known odd-even effects in calm

Most associate liquid crystals with their everyday use in laptop computers, mobile phones, digital cameras, and other electronic devices. However, in contrast to their rodlike (calamitic) counterparts, first described in 1907 by Vorlander, disklike (
