英文摘要: The monolayer of racemic amphiphiles is studied as a film of cholesteric liquid crystal (ChLC), mixed by the left- and right-handed chiral enantiomers. The chiral phase separation (CPS) and molecular orientation pattern are analyzed by Bragg-Williams theory for binary mixtures and the curvature-elastic model of ChLC. It is shown that below a certain critical temperature a compression can induce transition from racemic phase to CPS phase with a stripe-pattern formation. This gives a clear explanation of CPS in a racemic monolayer recognized by Lundquist [Ark. Kemi. 17, 183 (1960)], and observed recently by Eckhardt ct al. [Nature (London) 362, 614 (1993)]. [S1063-651X(99)11301-1].
