“…The chiral twistane ring system, more correctly named tricyclo[4.4.0.0 3,8 ]decane, has been incorporated into a number of liquid-crystalline (R)-(+)-8-alkyltwistanyl-4-(trans-4-pentylcyclohexyl)benzoates or 4 -pentylbiphenyl-4-carboxylates (215)(216)(217); some of the members of these series are reported as showing chiral nematic phases [225]. The twistane ring system has D 2 symmetry and may be viewed as consisting of four fused boat form cyclohexyl rings, which all twist in the same sense; using the Cahn, Ingold, and Prelog selection rules, the two enantiomeric forms may be classified as having P-or M-helicity [92].…”
