A Family of Nanoporous Materials Based on an Amino Acid Backbone

Abstract

In the pocket: A nanoporous framework with internal surfaces lined with amino acid residues (see structure; Ni cyan, C gray (chiral centers yellow), H white, N blue, O red) is produced by the pillaring of nickel–aspartate layers by 4,4′-bipyridine. The presence of pockets capable of multiple interactions with guest species permits the enantioselective sorption of short-chain diols.
