Effect of pi–pi stacking on the self-assembly of azomethine-type rod–coil liquid crystals
The role of pi–pi stacking in the molecular self-assembly behaviour, the phase transitions and the fluorescent properties was investigated for coil–rod–coil liquid crystals with two ethylene oxide coil units and aromatic azomethine rod units. Three kinds of rod–coil liquid crystals with different rod units were synthesised and characterised by differentia...

Synthesis, Self-Assembly and Solution-Processed Field-Effect Transistors of a Liquid Crystalline Bis(dithienothiophene) Derivative
A new liquid crystalline dithienothiophene dimer cap-functionalized with 3,4,5-tris-n-dodecyloxyphenyl groups (1) has been synthesized. The absorption spectrum blue-shifts 7 nm, while the fluorescence spectrum redshifts 95 nm in thin film with respect to that in solution, suggesting that H-aggregate formation may occur and the molecules are cofacially aligned in the solid state. Compound 1 se...

Hierarchical mesoporous silica prepared from ethyl-cyanoethyl cellulose cholesteric liquid crystalline phase
Porous silica with hierarchical structures was prepared from ethyl-cyanoethyl cellulose/poly(3-(methacryloyloxy)propyl-trimethoxysilane) (E-CE)C/P(MPTOS) composites with fixed cholesteric liquid crystalline (LC) phase. The scanning and transmission electron microscopy (SEM and TEM) and N-2 sorption measurements results indicate that the silica prepared from cholesteric LC composites is of hie...

45. Phase separation dynamics and pattern formation in thin films of a liquid crystalline copolyester in its biphasic region
We present the experimental results concerning a phase separation dynamics and relevant pattern formation in thin film samples (ca. 10 μm in thickness) of a liquid crystalline copolyester in its biphasic region. The copolyester separates into an isotropic phase and an anisotropic phase in the biphasic region due to its composition heterogeneity, though it is homopolymer. The entire phase-s...

35. Lyotropic liquid crystal behavior of polystyrene-block-polyisoprene diblock copolymers in toluene as a truly neutral solvent
We present our experimental observations concerning lyotropic liquid crystal behavior and textures of the solutions of the two polystyrene-block-polyisoprene block copolymers in a truly neutral solvent (toluene). The block copolymers used either lamellar or cylindrical microdomains in bulk and also in solutions above the critical concentration (cc). The optical textures, such as fan-shaped te...

30. Phase-separated structures in polymer mixtures with a thermotropic liquid crystalline copolyester as one component: composition dependence
The composition dependence of the phase-separated structures in the polymer mixtures consisting of a thermotropic liquid crystalline (LC) copolyester (X-7G) and poly(ethylene terephthalate) (PET) was investigated by means of polarized light microscopy. For this purpose the mixtures were solution-cast into thin films, followed by isothermal annealing at 270 °C. Although the final structure...

27. Process and mechanism of phase separation in polymer mixtures with a thermotropic liquid crystalline copolyester as one component
The phase separation and the coarsening process of polymer mixtures with a thermotropic liquid crystalline polymer (LCP) as one component are investigated. The LCP used is a main-chain type copolyester X-7G, comprised of p-hydroxybenzoic acid (60 mol %) and ethylene terephthalate (40 mol %) units. The isotropic, transparent, and homogeneous test specimens of the 50/50 mixtures of X-7G and po...
