experimental part, p. 527 - 535 (2010/04/27)
We have synthesized new chiral liquid crystalline (LC) organic radical compounds 2 and 3, which are the derivatives of the previously reported compounds 1 containing a chiral cyclic nitroxide unit and an ester group in the mesogen core, and their ferroele

(Chemical Equation Presented) Enantiomerically enriched samples of chiral cyclic nitroxides with a 4-hydroxyphenyl group on the stereogenic center bearing the NO radical group undergo unprecedented spontaneous racemization and/or epimerization in aprotic solvents, which can be well accounted for by the multistep equilibrations involving planar quinoid intermediates.
Magnetic properties of all-organic liquid crystals containing a chiral five-membered cyclic nitroxide unit within the rigid core

Lining them up: Purely organic paramagnetic liquid crystals (see picture) showing thermally stable nematic or cholesteric phases were successfully prepared. The molecular orientation of the bulk liquid crystals induced by weak magnetic fields was confirme
