Discotic liquid crystals based on Cu(I) complexes with benzoylthiourea derivatives containing a perfluoroalkyl chain

Mesomorphic three-coordinate copper(I) complexes ([Cu(BTU)2X], where X Cl or Br) based on a new N-benzoylthiourea (BTU) ligand with two decyloxy and one perfluorooctyl groups at its periphery were designed and prepared. The BTU ligand coordinates via the S atom in a neutral monodentate fashion as confirmed by IR and NMR spectroscopy data. The liquid crystalline behavior of these copper(I) complexes was investigated by a combination of polarized optical microscopy (POM), differential scanning calorimetry (DSC), and X-ray diffraction analysis (XRD), while their thermal stability was studied by thermogravimetric analysis (TGA). These new copper(I) complexes have mesomorphic properties and exhibit a hexagonal columnar mesophase over a large temperature range, more than 100°C.

Novel supramolecular columnar liquid crystals based on thiosemicarbazides

Novel liquid crystal materials based on 3,4-di-n- alkoxybenzoylthiosemicarbazides (3a-h, n=5-10, 12, 14) were synthesised. The mesomorphic properties of these compounds were characterised and studied by differential scanning calorimetry, polarising optica

Mesomorphic behaviour of N-benzoyl-N′-aryl thioureas liquid crystalline compounds

A series of N-benzoyl-N′-aryl thiourea derivatives bearing alkoxy groups in terminal positions have been prepared and investigated for their potential liquid crystals properties. It was found that only the compounds which have only two alkoxy chains show calamitic mesomorphic behaviour, with nematic, smectic A and C phases being displayed. The type and stability of these mesophases are greatly influenced by the alkyl chain length. Successive introduction of additional alkoxy groups on the benzoyl moiety led to a significant decrease of the clearing points and suppression of the mesogenic character. Using of branched alkyl chain, 2-ethyl-hexyl, instead of normal alkyl group, led to the disappearance of mesogenic behaviour together with the lowering of the clearing temperature. The influence of chain length and number of chains is discussed.

A new family of bent-core C2-symmetric liquid crystals

A series of C2-symmetric compounds with different core sizes and varying lengths and numbers of alkoxy side chains were prepared, and the factors influencing their liquid crystalline mesophase behaviour were investigated. The compounds studied were based on benzophenone, dibenzylidene-acetone, and 1,9-diphenyl-nona-1,3,6,8-tetraen-5-one cores with either 1 or 2 linear alkoxy side chains. The side chains were varied in length from C6H13 to C12H25. The liquid crystalline mesophase behaviour of the compounds was investigated using differential scanning calorimetry, polarizing optical microscopy, and small-angle X-ray scattering (SAXS). It was found that a number of the molecules were able to self-assemble into smectic and nematic liquid crystalline phases.

Propeller-like hydrogen-bonded banana-melamine complexes inducing helical supramolecular organizations

The results of the study presented here show a new example of the use of liquid crystals and the interactions involved in the mesomorphic state to build up complex molecular organizations. We have pursued a design strategy in which hydrogen bonding allows

Lanthanide luminescent mesomorphic complexes with macrocycles derived from diaza-18-crown-6

Four tetracatenar (L1-L4) and one hexacatenar (L5) ligands, derived from the diaza-18-crown-6 framework, are synthesized and characterized. In these ligands, the amine functions are fitted with benzoyloxybenzyl linker groups, attached either with a carbon

Phasmidic phases in macrocyclic liquid crystals

In this article we describe the synthesis, characterisation and phase behaviour of some phasmidic liquid crystals containing the diaza 18-crown-6 macrocyclic core. Seven compounds were synthesised, five tetracatenar and two hexacatenar. The terminal alkoxy chains were varied in length from ten to eighteen carbon atoms, and the number of phenyl rings in the mesogenic units was set at either two or three. Depending on the nature of the mesogenic moiety, hexagonal columnar phasmidic and smectic phases were found to occur for these systems. The natures and structures of the columnar phases found for these systems are discussed in relation to the conformational structure of the macrocyclic core and to the overall geometry, shape and flexibility of the molecular structures.
