A fluid smectic A antiphase in a pure nitro rod-like compound
نویسندگان
چکیده
2014 A transition between a smectic A phase and a smectic A antiphase (SÃ) is observed for the first time in a pure compound : the nitrobenzoyloxybenzoate of heptylphenyl. So far, the anomalies of periodicities which are connected to this type of transition were only detected in cyano systems. Moreover, the solid phase of the inferior homologue of this nitro series is surprisingly influenced by similar anomalies of periodicities. J.

Generalization of the polymorphism with 2D fluid smectic phases
2014 On the basis of microscopic observations on free droplets we have located different transition lines between 2D fluid smectic phases in (x, T) binary diagrams. In particular a textural criterion has been defined to identify for the first time the SC-SÃ phase transition. Our studies lead to the classification of three 2D fluid smectics according to the following sequence : SC-SÃ-SAcre with ...
متن کاملNanostructures of liquid crystal phases in mixtures of bent-core and rod-shaped molecules.
We report small angle x-ray scattering (SAXS) studies of isotropic, nematic, and smectic mesophases formed by binary mixtures of bent-core (BC) and rod-shaped (RS) molecules. While optical studies indicate that the components are fully miscible, SAXS reveals fascinating structures that are consistent with segregation on a nanoscopic scale. We find that tilted smectic clusters, which have been p...
متن کاملDevelopment of polar order in liquid crystalline phases of a banana compound with a unique sequence of three orthogonal phases.
Alkyl substituted 4-cyanoresorcinol 1,3-bisbenzoates with terephthalate based rod-like wings show a series of three orthogonal smectic phases SmA-SmAP(R)-SmAP(A).
متن کاملUnusual bilayered fluid smectic modifications in polar series
2014 Through the description of three new series of polar compounds with a cyano or a nitro terminal group we progress in the generalization of the (x, T) binary diagrams dealing with bilayered fluid smectic phases. New arguments are put forward concerning the conspicuousness of the SAd-S A2 transition according to the structure of the SAd phase. For the second time a SA2~ SC2~ S? bilayer seque...
متن کاملFormation of smectic phases in binary liquid crystal mixtures with a huge length ratio
A system of two liquid-crystalline phenylpyrimidines differing strongly in molecular length was studied. The phase diagram of these two chemically similar mesogens, with a length ratio of 2, was investigated, and detailed X-ray diffraction and electrooptical measurements were performed. The phase diagram revealed a destabilization of the nematic phase, which is present in the pure short compoun...
