Planar chirality: a fascinating symmetry breaking which leads to ferroelectricity in ferrocenyl liquid crystals

Chuard, Thierry ; Cowling Stephen J. ; Fernandez-Ciurleo, Maria ; Jauslin, Isabelle ; Goodby, John W. ; Deschenaux, Robert

In: Chemical Communications (ChemComm), 2000, vol. 21, p. 2109-2110

We describe the synthesis, characterization and properties of the first optically-active 1,3-unsymmetrically disubstituted ferrocene derivative which is to exhibit smectic C* and smectic A* phases.

Campidelli, Stéphane ; Brandmüller, Torsten ; Hirsch, Andreas ; Saez, Isabel M. ; Goodby, John W. ; Deschenaux, Robert

In: Chemical Communications, 2006, vol. 41, p. 4282 - 4284

Polyaddition of mesogenic moieties to C60 were found to yield chiral supermolecular nanoparticles which exhibit iridescent helical chiral nematic phases.

Functional polypedes—chiral nematic fullerenes

Campidelli, Stéphane ; Eng, Carine ; Saez, Isabel M. ; Goodby, John W. ; Deschenaux, Robert

In: Chemical Communications, 2003, p. 1520-1521

Self-organising, functional materials created by bottom-up synthesis represent important steps forward in the development of novel materials, here we report on the preparation and properties of a chiral nematic tetrapedal liquid crystal that has been functionalised with C60.
