摘要：

Ion sensor: A highly dynamic poly(phenylacetylene) bearing α-methoxyphenylacetic acid (MPA) as chiral pendant exhibits selective helix induction and chiral amplification, and gives a material that acts as a sensor for the valence of metal cations. Selective coordination of the pendants with mono- or divalent metal cations determines the right- or left-handed helical sense of the polymer (see picture) and its chiroptical response.
