Self-assembly and Supramolecular Liquid Crystals based on Organic Cation Encapsulated Polyoxometalate Hybrid Reverse Micelles and Pyridine Derivatives
The controlled self-assembly of multi-components in one system represents the capability integrating intermolecular interactions and functions of components and is believed the key procedure leading to multifunctional materials finally. In pursuing this goal, we used a double-chain cationic surfactant with a benzoic acid group at the end of one tail to encapsulate Keggin-type polyanion clusters vi...

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...
