The molecular design, synthesis and characterization of the first examples of both classical and non-conventional chiral mesoionic (mesomeric + ionic) liquid crystals derived from sydnones are described. The occurrence of chiral smectic phases in these novel compounds was evidenced by optical microscopy, calorimetry and X-ray studies.
描述了从sydnones衍生出的经典和非常规手性中性离子型液晶的分子设计,合成和表征。通过光学显微镜,量热法和X射线研究证明了这些新型化合物中手性近晶相的存在。
