We have shown that cholesteryl nonanoate, a thermotropic compound which is well known to exhibit pretransitional effects at the smectic A (SmA) cholesteric (N*) transition (W.L. McMillan, Phys. Rev. A 4, 1238 (1971); 6, 936 (1972)), has in fact a TGB

The first compound for which the previously predicted biaxial nematic phase was claimed is 4-[3,4,5-tris(4-dodecyloxybenzyloxy)benzoyloxy]-4′-(4-dodecyloxybenzoyloxy)-1, 1′-biphenyl (I). This assignment was based on the observation of the optical

We have measured the molecular-attachment kinetic law for the interface velocity of the columnar hexagonal phase of the liquid crystal HET (hexaoctyloxyphenylene) when it grows into its isotropic liquid. This law is linear and characterized by a kine

Following our experimental observations of disclination lines in freely suspended droplets and free-standing films (Yu.A. Nastishin et al., Eur. Phys. J. E 5 353 (2001)), topological defects of the twist grain boundary (TGBA) phase are considered acc

International audience; We have measured the rheological properties of two cholesterol derivatives (cholesteryl myristate and cholesteryl nonanoate) in the vicinity of their cholesteric–smecticA transitions. The results for the two compounds differ

Pure fluorescent derivatives of 12-O-tetradecanoyl phorbol-13-O-acetate (TPA), labeled in the tetradecanoyl chain, are synthesized by two ways: 1) from both enantiomers of β-N-dansylaminotetradecanoic acid which requires the resolution of the (±)

The free growth (at constant temperature) of a columnar hexagonal liquid crystals is described. The chosen material is the hexaoctyloxytriphenylene. Three growth regimes are observed depending upon the value of the supersaturation Δ: a petal-shape r
