FERROELECTRIC, PYRAMIDAL LIQUID CRYSTALS |
| 摘要 |
Described are dodeca-substituted derivatives of the macrocyclic tetramers obtainable by means of the acid-catalysed condensation of pyrogallol and formaldehyde, wherein the substituents are alkanoyl chains. These substituted tetramers are optically anisotropic in the molten state and in particular show mesophases of pyramidal columnar type. |
