  摘要：

  (+)-4-(2-甲基丁氧基羰基)苯基 4-(5-烷基-1,3-二恶烷-2-基)苯甲酸酯 (12), (+)-4-(2-甲基丁氧基)-苯基 4-(合成了5-烷基-1,3-二恶烷-2-基)苯甲酸酯(11)和相应的1,3-氧噻烷(13, 14)和1,3-二噻烷化合物(15, 16)。测量了这些化合物的介晶行为。化合物12表现出铁电液晶行为(R=n-C11H23: -4 SmC* 94 °C)，而相应的1,3-氧噻烷(13, 14)和1,3-二噻烷化合物(15, 16)没有表现出这样的行为。因此，1,3-二恶烷化合物比1,3-氧杂噻烷或1,3-二噻烷类似物更有利于SmA向SmC*的转变。

• Monomers and their use for the production of a laser-optical recording
  申请人：BASF Aktiengesellschaft

  公开号：US05187298A1

  公开（公告）日：1993-02-16

  Novel laser-optical recording elements which can be repeatedly erased and recorded on contain recording layers (a) which exhibit enantiotropic, ferroelectric smectic liquid crystalline (S.sub.C*) behavior, so that they can be switched back and forth between two thermodynamically stable, optically distinguishable ferroelectric smectic liquid crystlaline S.sub.C* order states on exposure to a laser beam of sufficient luminous power, by applying an external electric field. The recording layers (a) themselves consist mainly or exclusively of novel polymers P having chiral mesogenic side groups. The novel polymers P are prepared using the novel monomers of the general formula I ##STR1## where R is hydrogen, chlorine or methyl, A is a flexible space-maintaining long-chain molecular moiety, and C is an optically active chiral molecular moiety and B is a mesogenic molecular moiety composed of at least three aromatic nuclei which are bonded linearly or virtually linearly to one another, or they are prepared using the novel monomers I which contain specially selected molecular moieties B in a novel combination with selected molecular moieties C.
