Synthesis and phase behaviors of side-chain liquid-crystalline polymers containing azobenzene mesogen with the different length alkyl tail

A series of side-chain liquid-crystal polymers, poly[6-[4-(4′-n-alkyl benzoateazo)phenoxy]-hexylmethacrylate]s (PMAzoCOORm, m = 1, 2, 3, 4, 5, 6, 8, 10, 14, and 18) have been prepared by two synthetic methods. The chemical structure of the monomers was confirmed by 1H NMR and mass spectrometry. The molecular characterizations of the polymers were performed with 1H NMR and gel permeation chromatograph. The phase behaviors of polymers were investigated by the combination of techniques including differential scanning calorimetry, polarized optical microscopy, and small-angle X-ray scattering. For m = 1, 2, 3, 4, 5, and 6, the polymers exhibited a monosmectic A phase in which the smectic layer period was almost identical to the side-chain length. In addition, for m = 2, 3, 4, and 5, they presented the monosmectic C phase in low temperature; moreover, the tilt angle increased from 23.3 to 40.5°. For m = 8, 10, 14, and 18, the polymers showed a bilayer smectic A phase in which the layer spacing was larger than a fully extended side chain but less than two extended chains. On the other hand, for the clearing point, with the increasing of m, it first decreased, and then increased. All of these indicated that the length of alkyl tails played an important role in the phase behaviors of these polymers.

Synthesis and Investigation of Mesomorphic Properties of Some Thiazole Derivatives

2,4-Disubstituted thiazoles with liquid crystal properties are synthesized.Influence of the length of the aliphatic chain on the type of mesomorphism and the width of the temperature range of the mesophase existence is investigated.The compounds are shown to possess mesomorphism of smectic type in the range of 36-145 deg C.

Smectogenic Salts Formed by Combination of Alkyl p-Aminobenzoates and p-Ethyl- or p-Chlorobenzenesulfonic Acid

Two series of smectogenic salts were obtained by combining alkyl p-aminobenzoates with p-ethyl- and p-chlorobenzenesulfonic acids, respectively.The shortest ester alkyl chain required to generate a smectic A phase is nonyl when the former sulfonic acid is employed but the chain may be as short as butyl when the latter is employed.The smectic A-isotropic transition temperature in the second series is significantly higher than that in the first series, indicating that the terminal substituent on the anion is as crucial as that in non-ionic mesogens in determining the mesophase stability. - Keywords: Smectic, alkyl p-aminobenzoates, benzenesulfonates

EFFECTS OF BRANCHING OF THE ALKYL CHAIN ON THE LIQUID CRYSTALLINE PROPERTIES OF N-(p-PHENYLBENZYLIDENE)-p-ALKOXYCARBONYLANILINES.

The liquid crystal behavior of twenty-three N-(p-phenylbenzylidene)-p-alkoxycarbonylanilines has been examined by optical microscopy and differential scanning calorimetry in order to study the effects of branching of the alkyl groups.
