Chirality Transformations from Chiral Mesogens to 2-D Chiral Monolayers

Abstract

Monolayer structures of a chiral mesogen, (R)-or (S)-[4'-(1-methylheptyloxy)-3'-nitrobiphenyl-4yl] 4-(trans-5-decenyloxy) benzoate, adsorbed on graphite were investigated with molecular dynamics simulations to clarify the mechanism of chiral supermolecular structure formation. We proposed a mechanism model that is based on the coupling between up-down symmetry breaking and the molecular tilt direction symmetry breaking of the monolayer.
