MOPping up ions : A synthetic ion channel formed with MOP‐18 transports protons and alkali‐metal ions across lipid membranes. Homogeneous, long‐lived single‐channel currents were observed in planar lipid bilayer experiments. The MOP‐18 channel prefers cations over anions, and the cation selectivity is in the order Li + ≫Na + >K + >Rb + >Cs + . This system is promising for applications such as sensors and catalysis.
