Introducing multiple functional groups into the pores of metal-organic frameworks
(MOFs) promise sophisticated properties. Precise control over the position of these
functional groups would enable the 3D chemical environment of discrete void spaces to be
tailored. This was an outstanding challenge prior to this work. In this thesis we present a
study of the synthesis, characterization and properties of MOFs that can meet this goal.
These MOFs are multicomponent in nature, being built up from three geometrically
distinct organic ligands. Functional groups can be appended to these ligands and are
incorporated in precise locations and with perfect order in the frameworks. The chemical
environment of the pores of these MOFs is “programmed” by these functional groups.
MOFs constructed in this way give rise to exceptional gas adsorption characteristics,
unexpected stability towards water vapour, and tunable catalytic properties.
