摘要：

Selective pores: Microporous dipeptide crystals can be used as single-crystal membranes. In permeation experiments with N2, 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 O2/N2 selectivities. (Figure Presented) © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
