Short
peptide sequences have been concomitantly folded into a specific helical
conformation and networked into a single crystal co-ordination material by
silver(I) co-ordination. The new
material contained two types of chiral nanochannel. The larger of the nanochannels, with a
diameter of around 2nm, offered a high degree of both chiral recognition and biomolecular
recognition. BF4-
counterions in the crystalline network could be exchanged with other anions in
a single-crystal-to-single-crystal transformation.
