Polycondensation in Mesomorphic Phases: Spinal Columnar Liquid Crystals Based on Octasubstituted Phthalocyanine Siloxane Derivatives

Résumé

Within the liquid crystalline domain, dihydroxysilicon(IV) octakis(dodecyloxymethyl) phthalocyanine is polycondensed to give a distribution of polysiloxanes. These latter form a mesophase with lamellar order. For the first time polycondensation has been carried out in a columnar mesophase and a new type of oligomeric mesogen has been obtained. The term spinal columnar liquid crystal is proposed to designate such a mesophase.
