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...
