Chiral molecule adsorption on helical polymers.
We present a lattice model for helicity induction on an optically inactive polymer due to the adsorption of exogenous chiral amine molecules. The system is mapped onto a one-dimensional Ising model characterized by an on-site polymer helicity variable and an amine occupancy one. The equilibrium properties are analyzed in the limits of strong coupling between helicity induction and amine adsorption and in that of noninteracting adsorbant molecules. We discuss our results in the context of recent experimental results.
