  Mesomorphic behaviour of N-benzoyl-N′-aryl thioureas liquid crystalline compounds

  摘要：

  A series of N-benzoyl-N'-aryl thiourea derivatives bearing alkoxy groups in terminal positions have been prepared and investigated for their potential liquid crystals properties. It was found that only the compounds which have only two alkoxy chains show calamitic mesomorphic behaviour, with nematic, smectic A and C phases being displayed. The type and stability of these mesophases are greatly influenced by the alkyl chain length. Successive introduction of additional alkoxy groups on the benzoyl moiety led to a significant decrease of the clearing points and suppression of the mesogenic character. Using of branched alkyl chain, 2-ethyl-hexyl, instead of normal alkyl group, led to the disappearance of mesogenic behaviour together with the lowering of the clearing temperature. The influence of chain length and number of chains is discussed. (C) 2010 Elsevier B.V. All rights reserved.

  Two series of phenylbenzylether and benzanilide based rod-like imidazolium bromides and their nonionic precursors, the 1-phenyl-1H-imidazoles have been synthesized and the influence of the number and length of the alkyl chain(s) and the structure of the linking group in the aromatic core (–CH2O–, –COO–, –CONH–) on their mesophase self-assembly in ionic liquid crystalline phases were studied by POM, DSC and XRD. Upon decreasing the length of the N-terminal chain or by enlarging the number and length of the C-terminal chains, the sequence smectic (SmA)–hexagonal columnar (Colhex)–micellar cubic (CubI/Pm3n) was found for the ether based imidazolium salts; while only SmA and Colhex phases were observed for the related amides. The influence of the polarity of the central linkages, namely –CH2O– and –CONH–, on the mesophase structure and stability is discussed and compared with related –COO– connected ILC.

  Six homologous series of novel ferroelectric liquid crystals containing α-methylcinnamoyl moiety in the core structure:(Remark: Graphics omitted.)(IA: k=1, l=1, (Remark: Graphics omitted.), n=8–16; IB: k=1, l=1, (Remark: Graphics omitted.), n=8–16; IIA: k=1, l=2, (Remark: Graphics omitted.), n=9–16; IIB: k=1, l=2, (Remark: Graphics omitted.), n=8–14, IIIA: k=2, l=1, (Remark: Graphics omitted.), n=9–16; IIIB: k=2, l=1, (Remark: Graphics omitted.), n=9–16) have been synthesized and their thermal and ferroelectric properties have been investigated. The mesomorphic transition temperatures and the spontaneous polarization for the homologous series (IA, IB, IIA, IIB, IIIA, and IIIB) depend on the core structure, the chiral group, and the terminal alkoxyl chain length. These homologous series show the chiral smectic C phase over wide temperature ranges including room temperature and the values of their maximum spontaneous polarization are in the range of 30 to 800 μCm−2. The thermal stability of the mesophase and the magnitude of the spontaneous polarization have been discussed from the view point of the molecular structure and the local molecular interactions.
