Abstract

Non‐symmetric lactate‐based chiral liquid crystal dimers containing an odd‐membered spacer are shown to exhibit a chiral twist‐bend nematic phase which is stable on cooling to room temperature. A comparison of racemic and optically pure materials reveals that the pitch length in the N*_TBphase is not influenced by molecular chirality, whereas the nematic‐twist‐bend nematic transition temperature is increased.
