Dipeptide Crystals as Excellent Permselective Materials: Sequential Exclusion of Argon, Nitrogen, and Oxygen

Abstract

Selective pores: Microporous dipeptide crystals can be used as single-crystal membranes. In permeation experiments with N2, O2, 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 O2/N2 selectivities. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
