Selective Artificial Transmembrane Channels for Protons by Formation of Water Wires

Lined up water molecules: Artificial transmembrane channels from pillar[5]arene monomeric and dimeric derivatives have been prepared. Single‐channel conductance measurements and isotopeeffect experiments under acidic conditions showed selective proton transport through the channels, which were media...

Zusammenfassung:Lined up water molecules: Artificial transmembrane channels from pillar[5]arene monomeric and dimeric derivatives have been prepared. Single‐channel conductance measurements and isotopeeffect experiments under acidic conditions showed selective proton transport through the channels, which were mediated by water wires formed in the pillar[5]arene backbones (see picture).
