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 confirmed by magnetic susceptibility measurements and EPR spectroscopy.
