Intrinsically chiral ferronematic liquid crystals
arXiv:2112.11887
Abstract
Strongly dipolar mesogenic compounds with a chiral center located in a lateral alkyl chain were synthesized, and shown to form the ferroelectric nematic phase. The presence of molecular chirality induced a helical structure in both the N and NF phases, but with opposite helix sense in the two phases. The relaxation frequency of the polar fluctuations was found to be lower for the chiral NF phase than for its achiral, non-branched counterpart with the same lateral chain length.
