Abstract

Modifying the outer surfaces of metal-organic frameworks (MOFs) has received considerably less attention than functionalization of the bulk, despite the range of physical and chemical properties that can be tuned by controlling MOF surface chemistry. In this Frontier article, we summarise developments over the last five years in both functionalizing and visualizing the outer surfaces of MOFs, with particular focus on their application as surface-modified nanoparticles for drug delivery and in the enhanced self-assembly of hybrid materials.

Highlights

Metal–organic frameworks (MOFs), network materials consisting of organic ligands connected by metal ions or clusters into multi-dimensional frameworks containing potential porosity,[1] have become one of the most studied classes of materials of the last twenty years.[2]

Over the past five years, the understanding of the chemical processes that occur at MOF surfaces has increased significantly, facilitating a range of applications centred on tuning the interaction of MOF particles with their bulk surroundings
