Amplification of enantioselectivity and sensitivity based on non-linear response of molecular wire bearing pseudo-18-crown-6 to chiral amines
Exploiting a non-linear response for chiral discrimination, an intelligent system capable of chirality amplification was designed and constructed as poly(phenyleneethynylene) having chiral pseudo-18-crown-6. Both sensitivity and selectivity were amplified from those limited by the law of mass action.
