Attempts to engineer cholesteric induction with chiral organic twist agents have proven difficult because of the complexity of the host-dopant interactions involved. In contrast, molecules such as binaphthols have been shown to result in high helical twisting power (HTP). Unfortunately, their application has been limited due to poor photostability. The preparation of photostable H8-BINOL analogues with sterically demanding conjugated moieties and their use as chiral dopants in liquid crystals will be presented.
