Abstract

Very selective: The cross-sectional area of the narrowest channel opening in an organic–inorganic porous ionic crystal that possesses one-dimensional channels is around 30 Å2. The compound sorbs molecules such as propane, 1-propanol, and 1,2-dichloroethane, which have cross-sectional areas smaller than the channel opening, while n-butane, 1-butanol, and 1,2-dichloropropane are excluded (see picture).
