2-(p-Substituted phenyl)-5-alkyl-1,3-dithianes, new liquid crystals, were synthesized by the thioacetalization of the corresponding aldehydes and dithiols. These compounds have characteristic supercooling states, exhibit monotropic liquid crystal phases even in the case of long terminal alkyl substituents. The mesomorphic characteristics of these compounds were different from those of the corresponding
2-(p-取代苯基)-5-烷基-1,3-二噻烷是一种新型液晶,通过相应的醛和二硫醇的硫缩醛化反应合成。这些化合物具有特征性的过冷状态,即使在长末端烷基取代基的情况下也表现出单向性液晶相。这些化合物的介晶特性与相应的1,3-二恶烷不同,这一定是由于硫和氧原子体积不同而导致分子宽度不同。
