• Synthesis and thermotropic liquid crystalline properties of calamitic molecules with laterally attached hydrophilic groups: Y-shaped three-block molecules which can form smectic and columnar mesophases

  The synthesis and the thermotropic liquid crystalline properties of calamitic mesogens (p-terphenyl derivatives, a biphenyl and a p-quintaphenyl derivative) with a laterally attached hydrophilic group (1,2-diol groups, primary and secondary amides, polyether chains, crown ether units, carbohydrate units, a hydrazide, a quaternary ammonium salt, a carboxylic acid and a sodium carboxylate) are reported. The compounds were investigated by means of polarizing microscopy and calorimetry. The influence of the type of the polar group, of the length of the rigid core and the position of the connection of the hydrophilic group with the rod-like rigid core have been investigated. Many of these amphiphilic molecules can form monolayer S A phases. If a sufficient amount of hydrogen bonding is available their mesophase stability can be higher than that of related compounds with other lateral substituents. Rectangular columnar mesophases can be found for compounds with rather large and flexible polar lateral substituents (polyether chains) fixed to the center of the rigid terphenyl unit. These columnar phases should represent ribbon phases resulting from the collapse of the smectic layers (modulated smectic phases). The proposed model is also related to that suggested for supermolecular structures of triblock copolymers. Thus, these molecules can be regarded as low molecular weight block compounds consisting of three different and incompatible molecular parts.

• TOWARD BORONATE ESTER MESOGENIC STRUCTURES

  This article describes efforts toward the development of a new core for calamitic mesogens based upon the introduction of an extended heteroaromatic boron-containing ring. A series of tri-catenar mesogenic boronate ester derivatives of the 2-phenyl-1,3,2-benzodioxaborole has been synthesized and characterized. The flat central core appeared to be a suitable feature for these derivatives to support anisotropic alignment. Additionally, these derivatives should possess an inherent dipole in the core. However, thermal analysis (polarized optical microscopy and differential scanning calorimetry) did not reveal any mesophases.

  The synthesis of a series of banana-shaped mesogenic structures has been carried out, in which the bend unit is formed by the 3,6-substitution of carbazole by 4-alkoxyphenyl moieties. The crystal structures of the methoxy and propyloxy derivatives are reported with an analysis of the N-H...pi interactions that are observed in the crystalline state. This analysis was aided by semi-empirical molecular orbital calculations. Additionally, the thermal analysis of the complete series has been carried out in order to investigate the phase properties of these materials. The 4-nonyloxyphenyl derivative displays two melting points by DSC and normal light microscopy, but yields non-birefringent liquids. The incorporation of photorefractive molecular units, such as carbazole. into anisotropic materials may offer many advantages over conventional electrical poling of photorefractive polymers.
