Abstract
The effects of axial chirality on the Langmuir film behavior at the air–water interface and the morphological features of Langmuir–Blodgett (LB) films of 1,1 ′-binaphthyl acid have been investigated by using surface pressure-area (π– A) isotherm measurement, Brewster angle microscopy (BAM), and atomic force microscopy (AFM). It is found that the chiral discrimination between S-enantiomeric and racemic films can be observed on pure water subphase. In contrast to the flat LB film of S-enantiomer, the racemic LB film exhibits the coexistence of both monolayer and bilayer.
