supporting information; experimental part, p. 14000 - 14001 (2011/01/11)
Block copolymers of poly(3-hexylthiophene) and a poly(arylisocyanide) were synthesized in a single pot via the addition of 2-bromo-3-hexyl-5- chloromagnesiothiophene followed by n-decyl 4-isocyanobenzoate to a solution of Ni(1,3-bis(diphenylphosphino)prop

New liquid-crystall derivatives of thiazole with smectic mesomorphism over the range 5-85°C have been synthesized. Data on the spatial structure of the compounds synthesized have been obtained by quantum-chemical calculations. The effect of geometric anisotropy of the molecules of substituted thiazoles on their mesomorphic properties has been investigated.
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
