Self-organization of mesomeric-ionic hybrid heterocycles into liquid crystal phases: a new class of polar mesogens.
The first mesoionic nematic and smectic A mesogens derived from sydnones that are characterized by both covalent and ionic features have been synthesized and evidenced by optical, calorimetric and X-ray diffraction studies.
