Enhanced stability in rigid peptide-based porous materials

Abstract

Pepped up: Notwithstanding the intrinsic conformational flexibility of peptides, [Zn(Gly-Thr)(2)] behaves as a robust porous metal-organic framework thanks to the rigidity introduced by the use of Gly-Thr (see scheme). This rigidity arises from the sequence of amino acids in the dipeptide that locks its conformational flexibility in the framework.
