摘要：

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 ferroelectric properties have been studied. The enantiomerically enriched (25,5S)-2 and (2S,5S)-3 showed an SmC* phase for which their ferroelectric properties such as spontaneous polarization (Ps) and tilt angle (theta) were compared with those of (2S,5S)-1.
