    • Although it might seem intuitive that the Δ-isomers would be more strongly adsorbed to the Δ-modified clay, it has been shown previously that the situation is reverse for certain tris- and mixed 1,3-diketonates of Ru(III) (ref 4).

    • The definition of Q being traceless, and consequently eqs 2 and 3, involves an approximation in which the isotropic contribution of a dopant is left out of consideration. In reality, effects of chirality are not necessarily canceled by the isotropic distribution, and Q is better regarded as anisotropic content of the surface chirality. For a full tensorial approach, see: Kuball, H.-G.; Höfer, T. In Chirality in Liquid Crystals: Kitzerow, H.-S., Bahr, C., Eds.; Springer-Verlag: New York, 2001; Chapter 3, pp 67-100.

The odd-even alternation in the HTP values of certain chiral dopants has been observed in the presence (at 20 mol %) of 4,4′- dialkoxyazoxyzenzenes in a nematic host, although the effect upon elongation from methoxy to ethoxy terminal groups is much weaker (2-5% diminution) in this case.
