Synthesis and mesophase characterization of novel methacrylate based thermotropic liquid crystalline monomers and their polymers

A new series of side chain methacrylate monomers with a three phenyl ring core connected by an ester with a terminal alkoxy chain and hexamethylene spacer are synthesized by a multistep synthetic route. The corresponding polymers are realized by free radical solution polymerization. Two structurally similar mesogens are also synthesized for use as models to study the influence of the methacrylic unit on the mesophase characteristics. The molecular structure of the intermediates, monomers as well as the polymers is unambiguously confirmed by Fourier-transform infrared (FT-IR), solution 1H and 13C nuclear magnetic resonance (NMR) spectroscopy and by elemental analysis. The mesophase characteristics of all of the monomers and polymers are determined by hot-stage optical polarized microscopy (HOPM) and differential scanning calorimetry (DSC). These investigations revealed the existence of enantiotropic nematic (N), smectic A (SA) and smectic C (SC) mesophases. Furthermore, for a representative monomer and polymer, the presence of the smectic phase is confirmed by variable temperature X-ray diffraction (XRD) where a characteristic layer ordering is noticed. The molecular weight of the polymers is determined by gel permeation chromatography (GPC) and the values are found to be typically in the range of 2.0 × 103 to 3.7 × 103. The mesogenic polymers are also found to be stable up to 320 °C by thermogravimetric analysis (TGA). the Partner Organisations 2014.

Ferroelectric and antiferroelectric switching behaviour in new unsymmetrical bent-core compounds derived from 3-hydroxybenzoic acid

Herein we report the synthesis and characterization of several achiral bent-core unsymmetrical compounds exhibiting mesomorphic properties. The lower homologues in two series of compounds show a columnar phase with a rectangular lattice whereas the middle

Liquid crystalline amides: Linear arrangement of rod-like molecules by lateral intermolecular hydrogen bonding and molecular shape effect

Bent- and straight-rod shaped liquid crystalline amides 1-3 were designed and synthesized, and their thermodynamic behaviors were investigated by polarized optical microscopy and differential scanning calorimetry, and their layer distances were measured by X-ray diffraction. Weak or strong hydrogen bonds were observed in variable-temperature FT-IR spectra for bent-rod shaped compounds 1 possessing a long alkoxy chain (OR2), straight-rod shaped compounds 2, and straight-rod shaped 3 in their smectic C, smectic C x, and smectic A phases, respectively. Thus, these liquid crystalline amides could generate linear molecular aggregates in their smectic layers by the lateral intermolecular hydrogen bonds.

1,1'-Disubstituted Ferrocene-Containing Thermotropic Liquid Crystals of Structure 5-C5H4)COOC6H4XC6H4OCnH2n+1>2> (X=OOC or COO). Influence of the Orientation of the Central Ester Function on the Mesogenic Properties

The two series I and II of 1,1'-disubstituted ferrocenes which differ by the direction of the ester function included the rigid organic part were synthesized and their liquid crystal properties examined.These latter were found to be strongly dependent on the orientation of the connecting ester group and on the alkyl chain.
