Abstract
AbstractThe spacings of the smectic layers are compared with the lengths of molecules of p‐substituted phenyl 4‐(trans‐4′‐n‐decylcyclohexyl) benzoates. It has been found that if the NO2, CN or CHO groups are substituted in the p‐position of the phenyl, then the smectic layers consist of dimers, whereas in the presence of the NCS, COCH3, I, Cl, Br, F substituents the smectic layers reveal a monomolecular spacing.
