Amino acid functionalized metal–organic frameworks by a soft coupling–deprotection sequence

Abstract

Covalent post-synthetic modification of a MOF, (In) MIL-68-NH(2), is carried out in a novel fashion to immobilize amino acids within the structure. Solid-phase peptide coupling methodology opens new perspectives for anchoring chiral bio- and catalytically active species. This could facilitate the immobilization of highly active and/or coordinating moieties inside MOF cavities.
