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.
