Semi-fluorinated p-terphenyl liquid crystals

p-Terphenyls carrying two or four fluorine atoms in the central ring were synthesized via Suzuki-Miyaura cross-coupling reaction using phenylboronic acids and fluorinated dibromobenzenes. By calorimetric and X-ray diffraction analyses it was found that th

New pyridine based liquid crystalline esters with different terminal chains

The synthesis, structural and mesomorphic characterization of new pyridine-based methyl esters carrying a n-alkoxy chain or 3,7-Dimethyloctyloxy branched group at terminal have been presented. The liquid crystalline properties of the new pyridine-based calamitic molecules have been investigated by polarized optical microscopy and differential scanning calorimetry. New compounds exhibit enantiotropic smectic A mesophase at a variable mesomorphic range depending on alkoxy chain length and branching at terminal. The presence of a branched terminal group in chiral or racemic form gives rise to a sharply increase in mesomorphic range as well as decrease in crystallization points by preserving mesophase type.

Synthesis and liquid-crystalline properties of methacrylate monomers carrying a p-terphenyl laterally substituted with one or two cyano groups

Two methacrylate monomers, carrying a p-terphenyl laterally substituted with one or two cyano groups, were synthesized and studied from the liquid crystal and optical points of view. The synthetic route involved several reactions, including the Suzuki rea

The interplay of soft-hard substituents in photochromic diarylethenes

A series of diarylethenes with substituents of different size and chemical nature was synthesised showing that beside some intermolecular interactions involving the central diarylethene core, lateral groups clearly play a key role in the crystal packing a

Glucose-Responsive Hybrid Nanoassemblies in Aqueous Solutions: Ordered Phenylboronic Acid within Intermixed Poly(4-hydroxystyrene)-block-poly(ethylene oxide) Block Copolymer

Coassembly behavior of the double hydrophilic block copolymer poly(4-hydroxystyrene)-block-poly(ethylene oxide) (PHOS-PEO) with three amphiphilic phenylboronic acids (PBA) differing in hydrophobicity, 4-dodecyloxyphenylboronic acid (C12), 4-octyloxyphenyl

Enthalpy-entropy compensation combined with cohesive free-energy densities for tuning the melting temperatures of cyanobiphenyl derivatives

This work illustrates how minor structural perturbations produced by methylation of 4′-(dodecyloxy)-4-cyanobiphenyl leads to enthalpy-entropy compensation for their melting processes, a trend which can be analyzed within the frame of a simple intermolecular cohesive model. The transformation of the melting thermodynamic parameters collected at variable temperatures into cohesive free-energy densities expressed at a common reference temperature results in a novel linear correlation, from which melting temperatures can be simply predicted from molecular volumes. In tune with temperature! The transformation of the melting thermodynamic parameters into cohesive free-energy densities (CFED) for 4′-(n-oxy)-i′-methyl-j-methyl-4-cyanobiphenyl (CnLi′,j) provides a novel linear correlation for predicting melting temperatures in a simple way.

Synthesis and polarized photoluminescence of novel phosphorescent cyclometalated platinum dimer

A novel phosphorescent cyclometalated platinum dimer with bis-[2-(p-dodecyloxyphenyl) pyridyl]-hexane-1,6-diol as ligand and 1,3-(1-n-hexyl,3-n-heptadecyl) diketone as ancillary ligand was synthesized. The chemical structure and liquid crystal property of

Columnar mesophases from half-discoid platinum cyclometalated metallomesogens

A series of liquid crystals have been synthesized and studied based upon mononuclear ortho-platinated rod-like heteroaromatic and 1,3-diketonate ligands. The liquid crystalline properties of these molecules were investigated using polarized light optical

Supramolecular dendrimers: Unusual mesophases of ionic liquid crystals derived from protonation of DAB dendrimers with facial amphiphilic carboxylic acids

Supramolecular liquid crystalline (LC) dendrimers were prepared by self-assembly of first to fifth generation amino terminated DAB dendrimers with facial amphiphilic carboxylic acids. These carboxylic acids are composed of three distinct incompatible segm

Synthesis and Properties of Liquid Crystalline 4,4 -Dialkoxy-2'-Methyl-p-Terphenyls

A new series of laterally substituted terphenyl compounds, 4,4 -dialkoxy-2'-methyl-p-terphenyls (n = 1-12), were synthesized. Their liquid crystallinities were characterized by means of polarizing optical microscopy (POM), differential scanning calorimetry (DSC), and X-ray difraction (XRD). The influence of the length of the terminal alkoxy groups on the liquid crystalline behavior was investigated. It was found that the compounds with shorter end chains (n a smectic A mesophase is exhibited for those with longer end chains (9 = n = 12).
