摘要：

Quantitative evaluation of geometrical chirality through the use of the Continuous Chirality Measure is employed to unveil correlations between chirality and several properties of helicenes. These include the efficiency of their chiral-chromatographic racemate separation, their optical rotation, their racemization energy and the melting points of the enantiomer-crystals. The non-monotonic behavior of the chirality of helicenes is shown to reflect the behavior of a theoretical helix. (C) 2000 Published by Elsevier Science Ltd.
