Abstract
1, 11-Dioxa [11] paracyclophane (2, 12-dioxabicyclo [11, 2, 2] heptadeca-13, 15, 16-triene) derivatives were thermally equilibrated in cholesteric mesophases. The enantiomeric and diastereomeric equilibria were biased to the extents of 0.4 and 3.6% (e.e.), respectively, independently of the macrostructural handedness of the mesophases.
