摘要
(Figure Presented) MOPping up ions: A synthetic ion channel formed with MOP-18 transports protons and alkali-metal ions across lipid membranes. Homogeneous, long-lived singlechannel 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. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
