Selective pores : Microporous dipeptide crystals can be used as single‐crystal membranes. In permeation experiments with N 2 , O 2 , and Ar, the main components of air, the crystals show high permeabilities and excellent selectivities (see picture). L ‐Alanyl‐ L ‐alanine crystals exhibit extremely high O 2 /N 2 selectivities.
