We report liquid crystals that show ferroelectric nematic phases. We have modified the bridged three-ring structure reported previously to investigate structure-property relationships. Small changes in the length of the flexible chain and variation of the bridge structure cause large differences in the phase sequence as well as in the ferroelectric-nematic transition temperatures. In addition, as a first step toward industrially relevant mixture design, a binary...
