Whereas their para homologs are not mesogenic, the disk-shaped triphenyltriazine meta-trialkylesters obtained via trimerization of 3-cyanobenzoic alkylester, which configurationally more flexible, exhibit a monotropic nematic mesophase. Introduction fluorine atoms into alkyl chains or phenyl moieties leads to appearance an enantiotropic columnar If is introduced both in and moieties, only mesop...

Inclusion of non-mesogenic pendant segments, such as alkyl, PEG and fluoroalkyl, at periodic intervals along the backbone main-chain LCPs, that contain flexible spacers, provides an interesting alternative to control mesophase structure layer periodicity.

We report on a chemical-sensing method based on the silica-micelle mesophase wherein both a fluoroionophore and a masking agent are embedded. Using this method, a highly selective detection of metal ions in an aqueous solution has been successfully demonstrated. Furthermore, simultaneous analyses of multisamples using a sensor array composed of functionalized mesoporous thin films were demonstr...

The carrier mobility of highly ordered lamellar mesophases was evaluated by a Time-of-Flight (TOF) method for mesogenic 1,4-di(5'-octyl-2'-thienyl)benzene (8-TPT-8) to reveal the fastest drift mobility (0.1 cm(2) V(-1) s(-1) for the lowest temperature mesophase) in calamitic liquid crystals reported to date.

The composition distribution of slurry oil has a significant impact on the structure and performance mesophase. In this study, supercritical fluid extraction (SFEO) components were extracted from two oils (SLOs) using (SFE) technique. fundamental properties SLOs associated SFEOs thoroughly investigated. Electron microscopy spectroscopic techniques employed to study morphology structures mesopha...

Small angle X-ray scattering studies of 2nd and 3rd generation based extended amphiphilic dendrons in the shape of macromolecular dumbbells with identical hydrophilic volume fractions suggest 2-D hexagonal columnar and Pm3n micellar cubic mesophases, respectively, elucidating the role of shape induced interface curvature in mesophase formation.
