| Outline of Final Research Achievements |
We designed new bistolane nematic liquidc crystals with alkylsulfanyl groups for extraordinary birefringence materials. A symmetric derivative contains short terminal methylsulfanyl groups (SCH3) on both ends, while two asymmetric derivatives contain a methylsulfanyl group on one end, as well as a highly polarizable cyano (CN) or isothiocyanate (NCS) group on the other end. These materials exhibited a well-defined enantiotropic nematic phase, as well as an extremely high birefringence (Δn > 0.6). Most notably, the NCS derivative achieves an extremely high value of 0.77 at 550 nm.
