Abstract

original image

Along narrow channels: Mutual integration of a microporous coordination polymer and histamine provides a proton conductivity above 10−3 S cm−1 under anhydrous conditions. Anisotropic alignment of histamine molecules in straight 1D channels creates a specific conduction pathway (see picture).
